| Summary: | The Er3+/Nd3+ doped glasses of the form (69-x)TeO2-15Li2CO3-15Nb2O5-1Er2O3-(x)Nd2O3 with x=0.4, 0.8 and 1.0 mol % are successfully made by using conventional melt-quenching technique. It was found both the photoluminescence intensity and stimulated emission cross-section were found increase with Nd3+ codoping. Efficient blue (497 nm,2 G9/2 →4 I9/2), green (550 nm,2 G7/2 →4 I9/2), orange (618 nm,2 H11/2→4 I9/2), and red (635 nm,4 F9/2→4 I9/2) spectra were observed. The results suggest that the present glass shows the potential candidate of broadband amplifiers and lasers as it is comparable with other Nd3+ doped other host.
