Предметные рубрики: Energy-transfer Diodes Ions Eu3+ Photoluminescence Reduction Tb3+ Ключевые слова (''Своб.индексиров.''): babpo5--eu2+--phosphor--white light emitting diodes Аннотация: Blue-emitting BaBPO5:xEu2+ phosphors were prepared by a high-temperature solid-state reaction route. The crystal phase, luminescence properties, lifetime, and thermal stability were investigated, respectively. The phase analysis indicated that BaBPO5 crystallize with the structure of stillwellite-type compounds. Under the excitation at 310 nm, the phosphor exhibited an asymmetric broad-band blue emission with peak at 410 nm, which was ascribed to the 4f-5d transition of Eu2+. It was further calculated that the dipole-dipole interactions were responsible for a concentration quenching effect in BaBPO5:xEu2+ phosphors at x = 0.08. The lifetime decreased with the increasing concentration of Eu2+ ions. The temperature-dependent emission spectra indicated an excellent thermal stability of the BaBPO5:0.08Eu2+ samples. Surface morphology and CIE coordinate were also investigated. All the properties assessed indicated that the developed blue-emitting BaBPO5:Eu2+ phosphor is a good candidate for application in white-light emitting diodes. © 2016 by American Scientific Publishers.
