• Luminescence spectra of potassium-alumina-borate glass with copper.
• Blue shift of the spectra by 100 nm during heating from 20 up to 300 °C.
• During heating intensity decreases less than 5% when excited by 405 nm.
It is experimentally shown that a considerable luminescent thermochromic effect occurs in potassium-alumina-borate (PAB) glasses with copper-containing molecular clusters. This effect is manifested in a reversible blue spectral shift of luminescence band about 100 nm and its narrowing, with negligible change of luminescence amplitude in maximum during heating from 20 up to 300 °C. Luminescence and excitation spectra of PAB glass at different temperatures are presented. It is shown that the temperature rise results in a red spectral shift of excitation bands and in their broadening.
