Growth and Characterization of a Novel Organometallic Nonlinear Optical Crystal: Bis(Thiourea) Cadmium Formate

Abstract

The growth of a novel organometallic nonlinear optical (NLO) crystal of thiourea complex bis(thiourea) cadmium formate (BTCF) in larger size is reported for the first time by the slow evaporation method. The grown crystal was subjected to single-crystal X-ray diffraction, morphology, optical transmission, Fourier transform infrared (FT-IR) spectroscopy, second harmonic generation (SHG) efficiency test and microhardness studies. The powder SHG efficiency of BTCF is comparable with KDP.
