Effect of Gamma Irradiation on Optical Properties of Cerium Doped Phosphate Glasses
نویسنده
چکیده
Transparent bubble free phosphate glasses with composition 50P2O5-10Al2O3-20CaO-(20-x)Na2O-xCeO2 (x varying from 0 to 4 mol %) have been prepared using melt quenching technique. The amorphous nature of the prepared glass samples has been confirmed from XRD spectra. The optical absorption coefficient has been determined from the UVvisible absorption spectra. The prepared glass samples have been irradiated with gamma rays of dose up to 100 kGy. The XRD spectra revealed that there was no change in the amorphous nature of glasses with irradiation. The absorbance was found to increase with the gamma irradiation. Thus, these glasses can be used as shielding materials.
