Monocrystal growth, X-ray diffraction, photoluminescence, thermal and dielectric studies of cadmium thiourea acetate complex doped with l- cystine

Single crystal of l-cystine (LC) doped cadmium thiourea acetate (CTA) material has been grown by slow solution evaporation technique. The crystalline phase and structural parameters of LC doped CTA crystal has been evaluated using the powder X-ray diffraction technique. The color centered emission in grown crystal has been examined in the visible region of interest using the photoluminescence study. The thermal stability and the melting point of LC doped CTA crystal has been investigated using the simultaneous thermogravimetric and differential thermal analysis (TG/DTA) technique employed in the temperature range of 50-500 °C. The dielectric properties of pure and LC doped CTA crystal has been comparatively investigated at different temperatures by means of dielectric measurement study.
