The heat treatment of glasses synthesized in the M(2)O-Ga(2)O(3)-GeO(2)-SiO(2) (M = Li, Na, K) system results in bulk precipitation of Ga(2)O(3) and LiGa(5)O(8) nanocrystals and, consequently, in luminescence within the bands with maxima at wavelengths of 1500 and 1300 nm, respectively, with the half-width exceeding 300 nm. In their spectral luminescence properties, the gallium germanium silicate glasses synthesized are similar to the gallium silicate glasses. However, the melting temperature of the former glasses is approximately 100 degrees C lower, which considerably facilitates the preparation of glasses of high optical quality.
