Luminescence properties of potassium aluminoborate glasses with copper(I) ions at cryogenic temperatures

Luminescence spectra of potassium aluminoborate glasses with copper(I) ions have been recorded in the temperature range from +20 to −196°C. It is shown that a decrease in the glass temperature gives rise to thermochromic luminescence, which manifests itself as a red shift of the luminescence band, a value of which reaches 95 nm. This spectral shift is accompanied by a decrease in the luminescence-band amplitude by 30%.
