The Synthesis and optical characterization of Nd3+ doped Na2O–TeO2–ZnO glass
Nd2O3 was incorporated into Na2O–TeO2–ZnO glass by a melting method in air atmosphere. The absorption and photoluminescence spectra of the transparent glasses, was studied. The measurement of optical properties was obtained by using a double beam optical spectrophotometer with an integrating sphere in the wavelength range 300 to 1100 nm. The absorption characteristics of Nd3+ doped samples clearly revealed the absorption due to Nd3+ ions. On the other hand the samples showed enhanced absorption due to 4F7/2® 4F5/2 transition. The absorption and emission cross section for 4F7/2® 4F5/2 of Nd3+ were estimated. Results of absorption, emission and fluorescence lifetime (for the 4F3/2–4I9/2 transition) were presented for the prepared glass doped with 1 wt% concentrations of Nd2O3. Also the results of the investigations with essential discussions and conclusions have been reported here in this paper.
