Optical properties of erbium doped tellurite glass with different NaCL composition

A series of glasses based on (79.5-x)TeO2-20Na2O-(x)NaCl-0.5Er2O3 (where x = 0.0, 2.5, 5.0, 7.5 and 10.0 mol %) are successfully prepared by melt quenching technique. The amorphous nature of the glass have been characterized using X-ray Diffraction technique and the optical properties are characteri...
