Structural, optical, and spectroscopic properties of Er3+-doped TeO2-ZnO-ZnF2 glass-ceramics

Transparent fluorotellurite glass-ceramics have been obtained by heat treatment of precursor Er-doped TeO2-ZnO-ZnF2 glasses. ErF3 nanocrystals nucleated in the glass-ceramics have a typical size of 45±10nm. Based on the Judd-Ofelt theory, the main radiative parameters for the 4I13/2→4I15/2 transitio...
