Zatsepin, D. Zatsepin, V. Solomonov, V. Guseva, S. Cholakh] Alkali silicate glasses of variable composition 22xNa2O · 22(1−x)K2O · 3CaO · 75SiO2 with equimolecular replacement of sodium ions by potassium ions are investigated using pulsed cathodoluminescence. It is revealed that localized electronic states interact with vibrations of two types, namely, polarization vibrations of the silicon-oxygen network with the frequency v0 = 820 cm−1 and bending vibrations of the modifier sublattice. At low concentrations of one of the alkali components (x < 0.1), bending vibrations are observed at two frequencies. These frequencies coincide with those of the corresponding vibrations in one-alkali systems containing Na (530 cm−1) and K (520 cm−1). At higher concentrations (x in the range ∼0.14-0.86), there occur bending vibrations of the cationic sublattice with a frequency of 420 cm−1. This can be interpreted as a luminescence analog of two-alkali (mixed-alkali) effect. Pleiades Publishing, Inc., 2006 Zatsepin A. Ural State Technical University, ul.
