Keywords: copper-cadmium photochromic glass | optical absorption | luminescence excitation | structure defects

The spectra of optical absorption, luminescence excitation and photoluminescence in the range of 200–750 nm in the Cu-Cd-photochromic glasses were measured. As a matrix of photochromic glass the sodium-borosilicate glass was used. The absorption within the UV wavelength range (200–300 nm) is connected to various structural defects of the matrix glass. The changes of the optical absorption and photoluminescence excitations resulting from the UV radiation in the Cu-Cd-photochromic glasses have been analysed. It was noticed the share of the matrix glass structure components in creation of the colour centers stable of room temperature.
