Аннотация: Произведен расчет энергетических спектров взаимодействия пары наночастиц CdSe в квазирезонансном электромагнитном поле, для случаев одинаковых частиц и частиц с отличающимися длинами волн переходов, использовано диполь-дипольное приближение. Показано, что учет дополнительных переходов значительно увеличивает величину энергии взаимодействия для потенциальной ямы, лежащей в длинноволновой области спектра. На примере двух частиц с ограниченным числом резонансов исследовано влияние разности резонансных длин волн на глубину и положение потенциальной ямы.
Spectral dependences of interaction energy of multilevel semiconductor quantum dots are calculated in dipole-dipole approximation for a pair of CdSe quantum dots in a quasi-resonant laser field, for cases of two identical quantum dots and those with differing transition wavelengths. Interaction energy of pair of multilevel quantum dots in the long-wavelength potential well is much higher than that of pair of two-level quantum dots.

Wavelength-controlled manipulation of colloidal quasi-resonant quantum dots under pulsed laser irradiation / A. S. Tsipotan [и др.] // Photonics Asia : Asia’s premier event on nanophotonics, biomedicine, lasers,optical design, plasmonics, sensors, optoelectronics infrared/terahertz, and more : advance technical program. - 2016. - Ст. 10027-35. - P. 39
Аннотация: Electrodynamical interaction between excited NPs is rather universal and allows formation of wide variety of nanostructures both of homo- and heterogeneous content. Experimental results are obtained for CdTe QDs with the excitonic resonance at 520 nm. Six different samples of the same colloid solution were irradiated at wavelengths from 540 to 570 nm. Modifications of absorption spectra of solutions after irradiation was detected, being most prominent at 555 and 560 nm irradiation wavelengths. Analysis of spectra shows that up to 47% of QDs were assembled into pairs. Therefore, possibility of precise QDs manipulation via laser-induced electrodynamical interaction is demonstrated.

Self-assembly -- nanostructures -- quantum dots -- absorption spectra -- dipole-dipole interaction -- laser control
Аннотация: Production of nanostructures consisting of semiconductor nanoparticles (NPs) is of interest for number of applications. Development of new methods of NPs' manipulation and aggregation of NPs into nanostructures with pre-defined geometry is also of considerable interest from the fundamental point of view. Under laser irradiation with properly chosen wavelengths excitonic excitations of semiconductor NPs will be induced. Electrodynamical interaction between excited NPs is rather universal and allows formation of wide variety of nanostructures both of homo- and heterogeneous content. Theoretical approach for study of interaction of NPs' ensembles with laser light includes dipole-dipole approximation for NPs' attraction. Experimental results are obtained for TGA stabilized CdTe QDs with the excitonic resonance at 520 nm. Six different samples of the same colloid solution were irradiated at wavelengths from 540 to 570 nm. Modifications of absorption spectra of solutions after irradiation was detected, being most prominent at 555 and 560 nm irradiation wavelengths. Analysis of spectra shows that up to 47% of QDs were assembled into pairs with 10 nm inter-QD distance. Therefore, possibility of precise QDs manipulation via laser-induced electrodynamical interaction is demonstrated.

Аннотация: This study considered a process of quantum dots' self-assembly into nanostructure arrays with predefined geometry, which proceeds in the external resonant laser field. We considered the simplest case of assembling a stable structure of two particles. The problem was solved numerically using a three-dimensional model of Brownian dynamics. The idea of the method is that the attraction of the dots occurs due to the interaction of resonantly induced dipole moments, with the dots being then captured by the Van der Waals force. Finally, a three-dimensional model was considered; the average nanoparticle aggregation time as a function of the laser radiation wavelength was calculated; the probability of such structures' being formed was estimated for the calculated average aggregation time and for the laser pulse duration used in the experiment. The wavelength of the maximum probability was found to be shifted from the single particle resonance wavelength of 525 nm to the red area of 535 nm, which is in qualitative agreement with the redshift of the resonance wavelength of interacting particles.

Аннотация: Self-assembly remains one of the simplest and cheapest methods of nanostructuring. And the dependence of the properties of the objects obtained, not only on their composition, but also on the form, brings to the fore the question of developing methods for forming structures of a predetermined form and searching for system parameters in which the formation of a structure becomes possible. This paper is devoted to modeling the process of self-assembly of a multiparticle nanostructure of a predetermined shape in the field of laser radiation.

Аннотация: Controlled self-assembly of plasmonic photonic nanostructures provides a cost-effective and efficient methodology to expand plasmonic photonic nano-platforms with unique, tunable, and coupled optical characteristics. Keeping advantages and challenges in view, this review highlights contemporary advancements towards the development of self-assembly of a plasmonic photonic nanostructure using a colloidal solution and a self-assembly modeling technique along with exploring novel optical properties and associated prospects. The potential applications of self-assembled plasmonic photonic nano-systems to investigate next-generation optoelectronic devices, the need to reduce and increase scaling up aspects, and improve the performance, are also covered briefly in the review. The need of considerable efforts for the design and development towards establishing novel cost-effective methods to fabricate controlled self-assembled smart nano-plasmonic platforms is also highlighted in this mini-review. Key confronting issues that precisely limit the self-assemblies of photonic nanostructures and desired integration with other device components, mainly including uniformity within miniaturized devices are also discussed. This review will serve as a guideline and platform to plan advanced research in developing self-assembled plasmonic photonic nano-systems to investigate smart functional optical devices.

Self-organised aggregation of a pair of particles with different resonant frequencies and electric dipole moments of transitions, controlled by an external quasi-resonant field / V. V. Slabko, A. S. Tsipotan, A. S. Aleksandrovsky // Quantum Electron. . - 2013. - Vol. 43, no. 5. - P. 458-462DOI 10.1070/QE2013v043n05ABEH015021
Аннотация: The influence of the oscillation phases of the dipole moments induced in metal nanoparticles and quantum dots by an external laser field on their interaction energy is considered. It is shown that a difference in resonant frequencies leads to the formation of additional minima and maxima, which are absent in the spectral dependence of the interaction energy of identical particles at similar orientations of the pair of particles with respect to the plane of polarisation of radiation. These features are due to the fact that the oscillation phase difference of the induced dipole moments of particles reaches values close to π.

Аннотация: The possibility of light-controllable formation of heterogeneous nanostructures containing resonant metallic and semiconductor nanoparticles is considered. Interaction energy between light-induced dipole polarization of nanoparticles at modest light intensity can be much more than the thermal motion energy. The configuration of self-assembled nanostructure can be controlled by the frequency and polarization of the light.
