- Abstract:
- The ultraviolet and infrared optical properties of glasses were studied when BaF, was substituted byBa(PO,), in fluoroaluminate glass by ultraviolet and infrared spectroscopy methods.Research indicates that,the introduction of Ba(P0, ) , can reduce the scattering and the absorption of crystal defects in glass，and cau-ses a migration of ultraviolet absorption edge to short wavelength.However， due to the intrinsic absorption，the ultraviolet absorption edge moves to long wavelength again with the increase of Ba(PO, ) , content， and theglass with 1% mole Ba( P0,) , content has the shortest ultraviolet cut - off wavelength.The phosphorus - oxy-gen bond( P - O) vibration produces a strong absorption peak at about 4700 nm， and the vibration of P - O -H bond results in the absorption peak of 5850 nm，that cause the shift of infrared absorption edge to shortwavelength direction. Influenced by hydrogen bonds，the absorption peak of hydroxyl group shifts to longerwavelength，and obviously broadened，reducing the transmission of glass in 3000 ~ 4000 nm scope.
