Spectroscopic Studies of Glasses Based on Rare-Earth Borates

摘要

Raman light scattering and Nd~(3+) luminescence are investigated in glasses based on rare-earth borates with a high content of the rare-earth oxide and subjected to annealing.It is established that,during annealing,structural relaxation brings about the formation of phases with a structure similar to the structure of rare-earth orthoborates and oxoborates.This leads to considerable changes in the characteristics of Nd~(3+) luminescence.
