MICROWAVE SYNTHESIS OF YTTRIUM OXIDE NANOSTRUCTURE POWDERS, DOPED WITH YTTERBIUM AND ERBIUM IONS

Abstract

Целью исследования была разработка микроволнового синтеза люминесцентных наноструктурированных порошков оксида иттрия, легированного ионами иттербия и эрбия (Y203:Yo Ег ) в процессе гомогенного осаждения из реакционной смеси хлоридов иттрия, иттербия и эрбия. Характеристики полученных порошков изучали методами рентгеновской дифракции, сканирующей и проходящей электронной микроскопии, дифференциально-термического анализа, ИК-спектроскопии и фотолюминесценции при ИК возбуждении. Из спектров люминесценции образцов Y2U3:Yb3+ уЕг , полученных при возбуждении ИК-лазером на длине волны 975 нм, установлено, что при изменении температуры обжига образцов цвет излучения порошков изменяется от зеленого до красного, что может быть использовано для производства люминофоров разного цвета. The aim of the study was to develop microwave synthesis of luminescent yttrium oxide powders doped with ytterbium and erbium ions (Y/JyYlr Er) in the process of homogeneous precipitation from a reaction mixture of yttrium, ytterbium ana erbium chlorides. The characteristics of the obtained powders were studied by X-ray diffraction, scanning and passing electron microscopy, differential thermal analysis, IR spectroscopy and photoluminescence under IR excitation. From luminescence spectra ofY203:Yb3+, Er samples obtained by excitation with an IR laser at a wavelength of975 nm, it can be concluded that when the calcination temperature of the sample's changes, the radiation color ofpowders changes from green to red, which can be used to produce phosphors of different colors.
