Abstract

ABSTRACT In present studies, L-arginine doped zinc thiourea chloride (LAZTC) crystal has been grown by slow solution evaporation technique. The cell parameters of LAZTC crystal were determined using the single crystal X-ray diffraction technique. The incorporation of L-arginine in ZTC has been confirmed by means of Fourier transform infrared analysis. The high optical transparency of the grown crystal has been examined under the UV-visible study. The wide optical band gap of LAZTC crystal is found to be 5.25 eV. The photoluminescence study of grown crystal has been investigated in the range of 300 to 700 nm. The negative photoconducting nature of LAZTC crystal has been investigated by means of photoconductivity studies. Thermal stability of LAZTC crystal was evaluated by thermogravimetric and differential thermal analysis. The dielectric measurements confirmed the lower dielectric characteristics of LAZTC crystal.
