Effect of EuF3 on Thermal and Luminescent Properties of Glasses in the 30BaZrF6-70NaPO3-EuF3 System

30BaZrF(6)-70NaPO(3) glasses doped with 0.1-1.0 wt % EuF3 have been synthesized. The introduction of up to 1.0 wt % EuF3 has no noticeable effect on glass formation and thermal and crystallization stability of the glasses. Heat treatment of glasses can lead to the formation of glass ceramics. Crystallization during the heat treatment of glasses occurs in two stages with the appearance of Na3ZrF7, NaZr(PO4)(3), and BaFPO3 crystalline phases in the glass phase. The presence of europium trifluoride in the glass is responsible for its luminescence, which increases without reaching saturation with increasing EuF3 content from 0.1 to 1.0 wt %.
