采用传统的固相法合成了一种新型的非线性光学材料--第一氟亚硒酸盐硝酸盐PbCdF(SeO_3)(NO_3)(NO_3)。该化合物在Pca21的极性空间群中结晶，其结构特征是由一维硝酸铅链和二维亚硒酸镉组成的新型二维层状结构。PbCdF(SeO_3)(NO_3)的倍频效率约为KDP的2.6倍，禁带宽度为4.42 eV。测得其激光损伤阈值为135.6 mW/cm~2，与文献报道的具有短紫外截止边的Li7(TeO_3)_3F相当。理论计算证实，四种功能单元的协同作用使PbCdF(SeO_3)(NO_3)成为一种引人注目的倍频材料。
A new nonlinear optical material, the first fluoride selenite nitrate PbCdF(SeO3)(NO3), was successfully synthesized by traditional solid state reactions. This compound crystallizes in the polar space group ofPca21, and its structure features a novel 2D layered structure consisting of 1D lead nitrate chains and 2D cadmium selenite layers. PbCdF(SeO3)(NO3) exhibits a phase-matchable SHG efficiency of about 2.6 times that of KDP and a wide band gap of 4.42 eV. Its laser damage threshold was measured to be 135.6 MW/cm2, which is comparative to that of the reported Li7(TeO3)3F with a short ultraviolet cutoff edge. Theoretical calculation confirmed that the synergistic effects of all the four functional units make PbCdF(SeO3)(NO3) a remarkable SHG material.
