摘要:: 在氟铝酸盐玻璃中引入Ba(PO3)2替代BaF2,采用紫外和红外光谱分析方法,研究了玻璃的紫外及红外光学性质.研究表明,引入Ba(PO3)2可以降低玻璃中晶体缺陷的散射和吸收,使玻璃的紫外吸收边向短波移动;由于本征吸收的影响,随着Ba(PO3)2含量的增加,玻璃的紫外吸收边重新移向长波,当Ba(PO3)2含量为1％摩尔时具有最短的紫外截止波长.磷氧键(P-O)振动在约4700 nm处产生一个强吸收峰,P-O-H键的振动导致产生5850 nm吸收峰,玻璃的红外吸收边带向短波方向移动;受氢键的影响,氢氧基吸收峰移向长波,并明显宽化,从而影响了玻璃在3000 ～4000 nm区域的光透过性能.

Abstract:: The ultraviolet and infrared optical properties of glasses were studied when BaF,was substituted byBa(P0, ) , 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.
