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.

Effect of concentration of QDs Cadmium Sulfide in Study of Optical Properties under Gamma Irradiation in Order to use in dosimetry

In this work, for the first time, effect of gamma irradiation on the optical properties of CdS (quantum dots) QDs in various concentrations was studied. The aqueous CdS QDs were synthesized in a facile and fast method by using domestic microwave oven.  Three concentration of QDs; 20, 2, 0.4 mg/cc after different administrated dose of gamma irradiation (0-20 kGy) were studied. The results showed...
