Abstract
A red photoluminescence emission band peaking at 1.95 eV is reported for Bi12SiO20 and Bi12GeO20. The mechanism for exciting the luminescence transition is considered, and a tentative model for the luminescence center is proposed. It is suggested that the most likely mode of excitation involves resonance transfer of energy from excitons to the luminescence center by means of a radiationless process followed by subsequent light emission from the luminescence center.This publication has 7 references indexed in Scilit:
