Синтез и исследование люминесценции оксидной керамики на основе оксида иттрия с переменным содержанием европия

Abstract

In this work, a study of yttrium oxide-based ceramics with a variable content of europium, obtained by the method of co-precipitation of layered hydroxonitrates at a constant pH of 7, followed by thermal decomposition was conducted. It was established that the addition of europium did not have a significant effect on the size and morphology of the powder particles, Europium was rather homogeneously distributed in the yttrium matrix over the whole con-centration range. The maximum luminescence intensity was observed for samples with the content of europium oxide of 10 % molar.
