Spectral studies of gel grown Ca2+ and Mg2+ doped cobalt cadmium oxalate single crystals

Single crystals of Ca2+ (CCoCO) and Mg2+ (MCoCO) doped cobalt cadmium oxalate were grown by single diffusion method in silica hydro gel at room temperature. Optimum conditions of the as grown crystals were established by varying Specific gravity of Sodium Meta Silicate (SMS), gel setting time, pH of the gel, concentrations of Oxalic acid and concentration of Ca2+ and Mg2+ solutions. Energy dispersive X-ray analysis (EDX) confirmed the presence of major elements such as Co2+, Ca2+, Mg2+, Cd2+ ions in the lattice of the grown crystals. Fourier transform infrared (FT-IR) spectrum exhibits the presence of OH, carboxyl group and metal-oxygen bonding. UV-Visible spectroscopic analysis measured the energy gap and insulating behavior of the crystals.
