Abstract
Nd3+- doped cadmium borate glasses were prepared and characterized optically. The oscillator strengths and Judd-Ofelt parameters for the glass containing 0.1, 0.3 and 0.5 wt% of Nd2¬O3 were computed. Density, refractive index and optical absorption spectra were measured. The values of Judd- Ofelt parameters suggested an increase in the degree of asymmetry the local ligand field at Nd3+ sites. The optical band gap energy and physical parameters was calculated for all glass samples. It was found that with increasing the concentration of Nd2O3 contents, the values of the optical band gap energy decrease.
