摘要

摘要: 为了探索硼磷酸钠（Na₅[B₂P₃O₁₃]，NBP）晶体可能具有的功能特性，发展适用不同光谱范围的硼磷酸盐材料，对其紫外-远红外光谱以及拉曼光谱进行了研究。实验测量了室温下NBP晶体在200~2 000 nm的紫外-可见-近红外透射和反射光谱、50~4 000 cm^-1远红外透射光谱以及拉曼光谱。首先根据光学常数间的关系，计算得到吸收系数、消光系数和折射率，并对计算得到的折射率采用Sellmeier方程进行拟合。然后分析由紫外到远红外的宽频透射光谱，最后对晶体的拉曼振动峰进行了指认。研究结果表明：在200~2 000 nm波长范围内最大吸收系数为3.1 cm^-1，消光系数数量级为10^-6，折射率在1.56~1.80之间，得到Sellmeier方程。在105~120 THz和150~375 THz频率范围内晶体透射率大于80%，在1.5~71 THz的声子吸收带的透射率几乎为零。晶体可作为某些波段的光学窗口材料或者特定波段的滤波器。

Abstract: In order to determine the latent function of an Na₅[B₂P₃O₁₃] crystal, its ultraviolet-far-infrared spectra and Raman spectra are studied. The ultraviolet-visible-infrared and far-infrared spectra and Raman spectra of an Na₅[B₂P₃O₁₃] crystal were measured at room temperature in the range of 200 to 2 000 nm and in the range of 50 to 4 000 cm^-1. The results show that the maximum absorption coefficient is 3.1 cm^-1, the extinction coefficient is in the order of 10^-6 and the refractive index is 1.56 to 1.80. Its Sellmeier equation is then obtained. In the frequency ranges of 105 to 120 THz and 150 to 375 THz, the transmittance is more than 80%, but in the frequency range of 1.5 to 71 THz, the transmittance is nearly zero. It is possible that the Na₅[B₂P₃O₁₃] crystal can be used as an optical window material or filter in some frequency ranges.
