Термохимический синтез ультрадисперсных порошков иттрий-алюминиевого граната, соактивированных церием и серой

Abstract

Изучен новый метод формирования ультрадисперсных порошков иттрий-алюминиевого граната, солегированного церием и серой, путем термохимического синтеза (горения). Размеры частиц Y3Al5О12 : Ce, S для порошка, синтезированного в смеси тиокарбамида и гексаметилентетрамина, составляют 14 нм–0,47 мкм в зависимости от температуры прокаливания. Показано, что полученные материалы, синтезированные методом горения, обладают яркой желто-зеленой люминесценцией с максимумом на длине волны 560 нм при возбуждении при λ = 440 нм, а интенсивность люминесценции зависит от температуры прокаливания и состава газовой среды. The article shows a new method of forming ultra-dispersed powders of yttrium-aluminum garnet, salted with cerium and sulfur, by thermochemical synthesis (combustion). The particle sizes of Y3Al 5O12 : Ce, S for the powder synthesized in the mixture of thiocarbamide and hexamethylenetetramine are 14 nm–0.47 μm depending on the calcination temperature. It has been shown that the obtained materials synthesized by the combustion method have bright yellow-green luminescence with a maximum at a wavelength of 560 nm at excitation at γ = 440 nm, and the intensity of luminescence depends on the calcination temperature and the composition of the gas medium.
