|
摘要
通过溶液法合成了一种非中心结构长条状的CsSbSO_4F_2晶体。其晶体结构属于空间群Pna2_1,结构中[SbO_2F_2]与[SO_4]多面体共顶点连接形成了一维链状结构,Cs+填充在长链之间维持电荷平衡。利用Kurtz-Perry方法对晶体进行粉末倍频测试,表明CsSbSO_4F_2属于可相位匹配的物质,其倍频效应约为KH_2PO_4的0.65倍。紫外-可见光-近红外漫反射光谱显示,该物质的截止波长为233 nm。光学性能测试表明,CsSbSO_4F_2在紫外区域有潜在应用。
A rod-like crystal CsSbSO_4F_2 with noncentrosymmeric structure was successfully synthesized by a soluthion method. It crystallizes in space group of Pna21,and it features a chain structure constructed by [SbO_2F_2] and [SO_4] polyhedra via corner-sharing mode,with Cs+cations residing between the chains to maintain charge balance. According to the Kurtz-Perry method,powder second-harmonic generation( SHG) measurements show that CsSbSO_4F_2 is phase-matching with an SHG efficiency of approximately 0. 65 times that of KH_2PO_4. The UV-visible-NIR diffuse reflectance spectrum indicates that the cutoff wavelength of the material is 233 nm. Optical performance tests show that Cs Sb SO4 F2 has potential applications in the ultraviolet region.
