Growth, Optical and Thermal properties of Co2+ doped copper tartrate single crystals at different environmental conditions.

Abstract

Cobalt doped Copper Tartrate (CoCT) crystals were grown in silica gel medium using single diffusion methods at room temperature, passing semiconductor laser and passing various UV visible radiation. The optimum conditions were obtained by varying parameters such as gel concentration, pH of gel, gel setting time, the concentration of reactance. The presence of cobalt, copper, carbon, and oxygen is confirmed by the Energy dispersive X-ray spectroscopy (EDX). The crystals obtained, are regular or elongated shaped depending on the growth and environmental conditions. The grown crystals are characterized by FTIR and PXRD. TGA studies explain the thermal behavior of the grown CoCT crystal. UV-Vis-NIR transmission spectroscopic analysis measured the energy gap and, to study the optical transparency of the grown crystals.
