LUMINESCENCE STUDIES OF Er3+ IONS IN FLUORIDE,FLUOROPHOSPHATE AND PHOSPHATE GLASSES

Abstract
Absorption spectra, emission spectra and excitation spectra of Er3+ ions in fluoride glasses, fluorophosphate glasses and phosphate glasses were measured. The influence of glass hosts on the luminescence of Er3+ ions was explained. The effects of temperature and ion concentration on the luminescence of Er3+ ions in these host glasses were investigated, and the discussions about the intrinsieal and internal energy transfer of Er3+ ions were presented.
