ABSTRACT
Nowadays rare earth doped glasses are becoming very interesting among researchers due to their physical and optical properties. In the present work physical and optical parameters were computed for borosilicate glasses doped with Neodymium ion. The glass samples were prepared by conventional melt quenching technique. Their final composition is (50 – x) B2O3 - (10 + x) SiO2 – 10 Na2O – 20PbO – 10 ZnO- 0.3 Nd2O3 (where x = 0, 5, 10, 15, 20, 25, 30, 35 and 40). The amorphous nature of the glass samples was confirmed by XRD (X-ray diffraction). Composition and functional groups of the glass samples were confirmed by EDX (Energy-dispersive X-ray spectroscopy) and FTIR (Fourier transform infrared spectroscopy) respectively. SEM (Scanning Electron microscopy) and TEM (Transmission electron microscope) images were recorded. Absorption spectra have been recorded at room temperature in UV-VIS-NIR region. Energy and intensity parameters were computed for Nd3+ doped glasses. Physical parameters were measured for the present glass. The optical energy band gap was computed for all different concentration of SiO2 contents. It was found that with increasing of the concentration of SiO2 contents, the values of physical parameters decreases.
