The Electron Spin Resonance (Esr) Spectra of Potassium-Alumina-Borate Glass Doped with Copper Ions

Abstract

We investigate electron spin resonance (ESR), absorption, and photoluminescence spectra of potassium-boron copper-containing glasses. In previous works it was found, that the considered glasses demonstrate a red shift of photoluminescence. In present work, we provide an evidence on the formation in glasses specific copper-containing structures that can be responsible for the red shift of photoluminescence “copper” band.
