HALIDE PEROVSKITE NANOCRYSTALS
RECENT PROGRESS
DOPING MN2+
Аннотация: Organic–inorganic metal halides have become a multifunctional platform for manipulating photoluminescence due to highly efficient and tunable emissions, especially for lead-free Mn2+-based halides. Herein, the zero-dimensional (0D) bromides of (C5H14N3)2MnBr4 and (CH6N3)2MnBr4 with different coordination environments were designed and synthesized by a solvent evaporation method. They exhibit green and red broadband emission peaks at 528 nm and 627 nm with high photoluminescence quantum yields of 86.83% and 61.91%, respectively, which are attributed to the d–d transition (4T1(G) → 6A1(S)) of [MnBr4]2− tetrahedral and [Mn3Br12]6− octahedral units. The cases emphasize the effect of organic ligands on the intrinsic emissions of Mn2+ ions, thereby revealing the luminescence mechanism of Mn2+ ions in 0D isolated structures through the Tanabe–Sugano (TS) energy diagram. Thanks to their bright and stable emissions, the fabricated white light-emitting diode (LED) based on (C5H14N3)2MnBr4 and (CH6N3)2MnBr4 provides an outstanding color rendering index (Ra) of 90.8 at a correlated color temperature (CCT) of 3709 K, along with the CIE chromaticity coordinates of (0.3985, 0.3979) and a luminous efficacy of 51.2 lm W−1. This work aims at clarifying the relationship between the coordination units of Mn2+ and tunable emissions, and in particular, proposes a new strategy to explore phosphors excited by blue light for white LEDs.

Density-functional theory study of the electronic structure of thin Si/SiO2 quantum nanodots and nanowires / P. V. Avramov [et al.] // Phys. Rev. B. - 2007. - Vol. 75, Is. 20. - Ст. 205427, DOI 10.1103/PhysRevB.75.205427. - Cited References: 63 . - ISSN 1098-0121

Аннотация: The atomic and electronic structures of a set of proposed pentagonal thin (1.6 nm in diameter) silicon/silica quantum nanodots (QDs) and nanowires (NWs) with narrow interface, as well as parent metastable silicon structures (1.2 nm in diameter), were studied using cluster B3LYP/6-31G(*) and periodic boundary condition (PBC) plane-wave (PW) pseudopotential (PP) local-density approximation methods. The total density of states (TDOS) of the smallest quasispherical QD (Si-85) corresponds well to the PBC PW PP LDA TDOS of the crystalline silicon. The elongated SiQDs and SiNWs demonstrate the metallic nature of the electronic structure. The surface oxidized layer opens the band gap in the TDOS of the Si/SiO2 species. The top of the valence band and the bottom of conduction band of the particles are formed by the silicon core derived states. The theoretical band gap width is determined by the length of the Si/SiO2 clusters and describes the size confinement effect in the experimental photoluminescence spectra of the silica embedded nanocrystalline silicon with high accuracy.

Effect of cobalt concentration on the magnetic properties of the Co1–xMgxFe2O4 nanocrystals / O. S. Ivanova, I. S. Edelman, S. G. Ovchinnikov [et al.] // JETP Lett. - 2024. - Vol. 119, Is. 2. - P. 104-110, DOI 10.1134/S0021364023603457. - Cited References: 26. - The research was carried out at the expense of the Russian Science Foundation Grant # 23-22-10025, https://rscf.ru/project/23-22-10025/, Krasnoyarsk Regional Science Foundation . - ISSN 0021-3640. - ISSN 1090-6487
Аннотация: Nanoparticles of Co1–xMgxFe2O4 with x equal to 0, 0.2, 0.4, 0.6, 0.8 and 1.0 have been synthesized. For all values of x, they are nanocrystals with a cobalt ferrite structure and an average linear size (56 ± 3) nm. Based on the analysis of the Mossbauer effect spectra, the Co2+ ions were shown to occupy only octahedral positions at all values of x. The experimentally obtained dependence of the nanoparticles magnetization on x corresponds to the dependence calculated using the Mossbauer effect data, except for the sample with x = 1.0. The effective magnetic anisotropy constant estimated for 0 K from the analysis of the coercive force temperature dependences decreases from 5.27 × 106 at x = 0 to 1.29 × 106 erg/cm3 at x = 0.8 and drops sharply to 4 × 104 erg/cm3 at x = 1.0

Аннотация: Self-assembled growth of α-FeSi2 nanocrystal ensembles on gold-activated and gold-free Si(001) surface by molecular beam epitaxy is reported. The microstructure and basic orientation relationship (OR) between the silicide nanocrystals and silicon substrate were analysed. The study reveals that utilisation of the gold as catalyst regulates the preferable OR of the nanocrystals with silicon and their habitus. It is shown that electron transport from α-FeSi2 phase into p-Si(001) can be tuned by the formation of (001)-or (111)-textured α-FeSi2 nanocrystals ensembles. A current-voltage characteristic of the structures with different preferable epitaxial alignment (α-FeSi2(001)/Si(100) and α-FeSi2(111)/Si(100)) shows good linearity at room temperature. However, it becomes non-linear at different temperatures for different ORs due to different Schottky barrier height governed by a particular epitaxial alignment of the α-FeSi2/p-Si interfaces.

Аннотация: Iron oxide magnetite (Fe3O4) should be a reasonable analog for conception and understanding of the magnetic properties of iron sulfide greigite (Fe3S4)—one of the most required magnetic materials having numerous applications but being far from the complete understanding now. We present here a comparative study of the Mössbauer effect (ME) and the magnetic circular dichroism (MCD) spectroscopy of Fe3O4 and Fe3S4 nanoparticles. The ME spectrum parameters of Fe3S4 are shown to distinguish strongly from that of Fe3O4, and the MCD spectrum shapes are shown to be absolutely different for two compounds. To clarify the origin of the Fe3S4 MCD spectrum we have performed ab initio band structure calculations and identified the MCD spectrum features with the transitions between calculated energy states.

Аннотация: We present in this report the route to produce highly-textured Au3Fe(111)/Fe(110) hybrid nanocrystals on an amorphous surface of SiO2/Si by molecular beam epitaxy. By controlling the quantity of Au atoms deposited onto the SiO2/Si it is possible to tune the average lateral size of resultant Au-Fe hybrid nanocrystals from 10-20 nm up to 100-150 nm at the same Fe nominal thickness deposited. This process is sensitive to the initial density and size of Au islands. Examination of Au-Fe hybrid nanocrystals obtained was carried out using X-ray diffraction, transmission and scanning electron microscopy, reflection high energy electron diffraction, and Kerr effect methods.

Аннотация: Self-organized α-FeSi2 nanocrystals on (100) silicon substrate were synthesized by molecular beam epitaxy with Au catalyst. The microstructure and basic orientation relationship between the silicide nanocrystals and silicon substrate were analyzed in detail. α-FeSi2 nanocrystals appeared to be inclined trapezoid and rectangular nanoplates, polyhedral nanobars and pyramid-like ones, aligned along 011 directions on (100) silicon substrate with the length up to 1.5 μm, width ranging between 80 and 500 nm and thickness from 30 to 170 nm. As has been proposed metallic iron silicide may be used for manufacturing electric contacts on silicon. A current-voltage characteristic of the structure was measured at room temperature and showed good linearity.

Аннотация: The incorporation of impurity ions or doping is a promising method for controlling the electronic and optical properties and the structural stability of halide perovskite nanocrystals (NCs). Herein, we establish relationships between rare‐earth ions doping and intrinsic emission of lead‐free double perovskite Cs2AgInCl6 NCs to impart and tune the optical performances in the visible light region. Tb3+ ions were incorporated into Cs2AgInCl6 NCs and occupied In3+ sites as verified by both crystallographic analyses and first‐principles calculations. Trace amounts of Bi doping endowed the characteristic emission (5D4→7F6‐3) of Tb3+ ions with a new excitation peak at 368 nm rather than the single characteristic excitation at 290 nm of Tb3+. By controlling Tb3+ ions concentration, the emission colors of Bi‐doped Cs2Ag(In1−x Tbx )Cl6 NCs could be continuously tuned from green to orange, through the efficient energy‐transfer channel from self‐trapped excitons to Tb3+ ions. Our study provides the salient features of the material design of lead‐free perovskite NCs and to expand their luminescence applications.

Аннотация: The atomic structure and physical properties of few-layered <111> oriented diamond nanocrystals (diamanes), covered by hydrogen atoms from both sides, are studied using electronic band structure calculations. It was shown that energy stability linearly increases upon increasing of the thickness of proposed structures. All 2D carbon films display direct dielectric band gaps with nonlinear quantum confinement response upon the thickness. Elastic properties of diamanes reveal complex dependence upon increasing of the number of <111> layers. All theoretical results were compared with available experimental data.

Аннотация: New law of the approach to magnetic saturation is proposed based on scaling in ferromagnets with random magnetic anisotropy. This law is consistent with the known laws derived within perturbation theory in extreme cases, but it describes the transition mode between the power-low asymptotic regimes better. The improved law is proper for reliable fitting the approach magnetization to saturation in nanocrystalline and amorphous ferromagnets. © 2017 Elsevier B.V.

   Перевод заглавия: Решеточное легирование ионами лантаноидов в нанокристаллах Cs2AgInCl6, обеспечивающее перестраиваемую фотолюминесценцию
Аннотация: Lead-free halide double perovskite Cs2AgInCl6 has become the research hotspot in the optoelectronic fields. It is a challenge to utilize the lattice doping by different lanthanide ions with rich and unique photoluminescence (PL) emissions for emerging photonic applications. Here, we successfully incorporated Dy3+, Sm3+, and Tb3+ ions into Cs2AgInCl6 nanocrystals (NCs) by the hot-injection method, bringing diverse PL emissions of yellowish, orange, and green light in Cs2AgInCl6:Ln3+ (Ln3+ = Dy3+, Sm3+, Tb3+). Moreover, benefiting from the energy transfer process, Sm3+ and Tb3+ ion-codoped Cs2AgInCl6 NCs achieved tunable emission from green to yellow orange and a fluorescent pattern from the as-prepared NC-hexane inks by spray coating was made to show its potential application in fluorescent signs and anticounterfeiting technology. This work indicates that lanthanide ions could endow Cs2AgInCl6 NCs the unique and tunable PL properties and stimulate the development of lead-free halide perovskite materials for new optoelectronic applications.

Кл.слова (ненормированные):
Hematite -- α-Fe2O3 -- optical absorption -- magnetic circular dichroism -- ellipsometric parameters -- Raman scattering -- one-ion d-d transitions -- pare exciton-magnon transitions
Аннотация: Hematite, α-Fe2O3, is a canted antiferromagnet with the Neel temperature of 960 K. The Morin transition, which occurs when the temperature is lowered to ∼260 K, when the magnetic moments of the sublattices become strictly antiparallel to each other and the resulting magnetic moment disappears, is a characteristic feature of this compound. Detailed investigations are presented here of the magneto-optical effects in the α-Fe2O3 nanoparticles in the transmitted light and in the α-Fe2O3 single crystal in the reflected light. Two types of magneto-optic features were revealed in the magnetic circular dichroism (MCD) spectrum. Some of them described by the Gauss line shape were associated with one-ion d-d transitions. Others were described by the S-shaped line with the inflection points corresponding to the absorption maxima. Last features were assigned to the pair exciton-magnon transitions. An exceptionally strong S-shaped line at 2.0-2.5 eV appeared to be a unique feature of α-Fe2O3 distinguishing it from other iron oxide compounds. The origin of the high effectiveness of the pair exciton-magnon interaction giving rise to this strong S-shaped feature in the MCD spectrum of α-Fe2O3 is discussed.

Аннотация: Dependences of relative saturation magnetization on temperature are measured for amorphous nanocrystalline ribbons of Finemet-type FeCu1Nb3Si13.5B8, FeCu1Nb3Si13B6, and FeCu1Nb3Si13B13 compositions. The character of the structural relaxation of amorphous alloys is established by means of Mossbauer spectroscopy, and the main magnetic characteristics are determined. It is found that the structural relaxation of amorphous ribbon proceeds in several stages upon annealing.
