Photoluminescence spectra of Er3+-doped fluorophosphate glasses

Abstract This short paper reports various physical, absorption and emission properties of the Er3+-doped glasses based on the (NaPO3)6 as the major constituent by changing the cations (Li, Na & K) both in mixed and unmixed forms. The obtained results show that the optical properties are found interesting in glass-B which contains, 20M% NRF as the network modifier.
