Abstract

The glass formation and crystallization of ErI3-doped melts in the Ag-Cs-Pb-X (X = I, Br, Cl) are investigated in the section corresponding to the cation ratio Ag: Cs: Pb = 59: 39: 2 with ErI3 contents of 0.2–7.5 mol %. The glass transition, crystallization, and melting temperatures are determined for a number of compositions. The primary crystalline phases that precipitate from melts upon crystallization are identified. It is demonstrated that the iodide, bromide, and chloride glasses containing up to 0.5 mol % ErI3 have the lowest crystallization ability. An increase in the ErI3 content leads to the precipitation of unidentified erbium-containing phases from melts upon cooling and to an increase in the crystallization ability of glasses. The spectral and luminescence properties of the glass of the composition 52Ag · 17AgCl · 39CsBr · 2PbCl2 + 0.5 mol % ErI3 are studied in the range of the 4 I 13/24 I 15/2 transition of the Er3+ ion. It is found that the lifetime of the 4 I 13/24 I 15/2 level of the Er3+ ion is equal to 10 ms.
