Silver phosphate glass types within composition 60P2O5-30ZnO-10CuO-1 ppm Ag2O were prepared by melt-quenching technique. The optical properties of these glass types were studied under UV exposure at different times, 0, 20, 80, 105, and 115 minutes. The optical absorbance spectra were measured in the range of wavelength from 190 to 3200 nm. The absorbance bandwidth decreases with increasing the time of UV exposure. The optical energy gap, E g , linear refractive index, n , ratio between molar refraction, R m , and molar volume, V m , and metallization criterion ( M ) were estimated. The value of E g decreases from 2.132 to 1.91 eV with increasing the time of UV exposure from 0 to 115 min. Otherwise n value and metallization increase with increase in the time of UV exposure. The results indicated that these glass types are promising for using an ultraviolet radiation dosimeter.
