采用实验和理论相结合的方法研究了硝酸铋Bi 2 O2 [NO3（OH）]（BINO）的结构特征和光学性质。采用水热法生长了BINO晶体，并对其紫外-可见吸收光谱进行了测量。粉末样品的二次谐波实验表明，BINO是一种相位匹配的非线性光学晶体，其粉末二次谐波系数高达2.3pm/V，这一点得到了第一性原理计算的证实。此外，给出了BINO非线性光学效应的结构起源。研究表明，BINO晶体在可见光和红外波段是一种很有前途的倍频晶体。(C)2012爱思唯尔有限公司保留所有权利。
The structural characteristics and optical properties of bismuth nitrate Bi2O2[NO3(OH)] (BINO) are investigated by experimental in combination with theoretical studies. The BINO crystal was obtained from the hydrothermal growth, and its UV-Vis absorption spectrum was measured. Second harmonic generation (SHG) experiments on powder sample show that BINO is a phase-matchable nonlinear optical crystal with a large powder SHG coefficient of 2.3 pm/V, which is confirmed by the first-principles calculations. Moreover, the structural origin of nonlinear optical effects in BINO is given. Our studies reveal that BINO is a promising SHG crystal in the visible and infrared spectral region.
