Spectral investigation of luminescence of glass in the 300?550 nm region

Luminescence characteristics of alkali borate glasses

“…Vibrational spectroscopy, such as infrared spectroscopy and Raman scattering spectroscopy, cannot solve this problem. This is due to the complexity of the decomposition of the spectra, the impossibility of clearly distinguishing in them bands which are related with the vibrations of nonbridge bonds, as well as a considerable error in calculating from the intensity of these bands the nonbridge-bond fraction [6].The luminescence of glass, as other dielectric materials and substances, is determined by impurities and structural defects of different kinds as well as the formation of centers of luminescence of different nature [7]. Recently, pulsed cathodoluminescence (PCL) has been widely used to study the luminescence properties of glasses [8 -9].…”
