Abstract

Single crystals of semi-organic optical material dibromo bis(triphenyl phosphine oxide)cadmium(II)[CdBr2(TPPO)2] were grown by low temperature solution growth method. The composition of grown crystals was confirmed on the basis of energy dispersive analysis of X-ray (EDAX). The optical band gap of the material was calculated from the UV–Visible–NIR spectral analysis performed. Dielectric constant and dielectric loss were measured as a function of frequency and temperature. Study confirmed the contribution of space charge polarization. Also, ac resistivity and conductivity were calculated. The growth features were observed by etching study.
