Abstract Single crystals of organometallic (DL)-trithioureatartrato- O 1 ,O 2 ,O 3 -cadmium(II) (TUDLC) have been grown from methanol solution by using the slow evaporation of solvent growth technique. The lattice structure and crystalline perfection have been determined by carrying out single crystal X-ray diffraction and high resolution X-ray diffraction measurements. The grown crystal was characterized thermally and mechanically by carrying out thermo-gravimetric and micro hardness measurements. The linear and nonlinear optical characterizations were made by carrying out optical transmittance, surface laser damage threshold, particle size-dependent second harmonic generation (SHG) efficiency and photo conductivity measurements. The grown crystal was electrically characterized by carrying out frequency-dependent dielectric measurements. Chemical etching study was also carried out and the dislocation density was estimated. Results obtained in the present study indicate that the grown TUDLC crystal is optically transparent with lower cut-off wavelength 304 nm, mechanically soft, thermally stable up to 101 °C and NLO active with SHG efficiency 2.13 (in KDP unit). The grown crystal is found to have considerably large size, good crystalline perfection, large specific heat capacity, higher surface laser damage threshold and negative photoconductivity.

有机金属 (DL)-酒石酸三硫脲-O1,O2,O3-镉 (II) 单晶的生长和理化性质

摘要 使用缓慢蒸发溶剂生长技术从甲醇溶液中生长了有机金属 (DL)-三硫脲酒石酸基-O 1 ,O 2 ,O 3 -镉(II) (TUDLC) 单晶。通过进行单晶 X 射线衍射和高分辨率 X 射线衍射测量，确定了晶格结构和晶体的完整性。通过进行热重和显微硬度测量对生长的晶体进行热和机械表征。通过进行光学透射率、表面激光损伤阈值、与粒度相关的二次谐波 (SHG) 效率和光导率测量来进行线性和非线性光学表征。通过执行依赖于频率的介电测量来对生长的晶体进行电学表征。还进行了化学蚀刻研究并估计了位错密度。本研究中获得的结果表明，生长的 TUDLC 晶体是光学透明的，具有较低的截止波长 304 nm，机械柔软，热稳定性高达 101 °C，NLO 有活性，SHG 效率为 2.13（以 KDP 为单位）。发现生长的晶体具有相当大的尺寸、良好的晶体完美度、大的比热容、更高的表面激光损伤阈值和负光电导性。
