Effect of Eu2O3 doping on the crystallization behavior of BaO-Bi2O3-B2O3 glasses

We gave studied the crystallization behavior of 30BaO · 25Bi 2 O 3 · 45B 2 O 3 glasses doped with Eu 2 O 3 to different levels. At a Eu 2 O 3 content of 7 mol % or higher, the glasses undergo volume crystallization. The only precipitating phase is a solid solution between europium and bismuth oxides...

Description
Summary:We gave studied the crystallization behavior of 30BaO · 25Bi 2 O 3 · 45B 2 O 3 glasses doped with Eu 2 O 3 to different levels. At a Eu 2 O 3 content of 7 mol % or higher, the glasses undergo volume crystallization. The only precipitating phase is a solid solution between europium and bismuth oxides. With increasing europium concentration in the glass, the structure of the crystallites changes from cubic to rhombohedral. We have investigated the morphology, physicochemical properties, and luminescence spectra of the glasses and glass-ceramics.
