Growth and characterization of pure and L-Glutamic acid doped zinc tris(thiourea) sulphate (ZTS) single crystals

Abstract

Single crystals of pure and L-glutamic acid doped zinc tris (thiourea) sulphate(ZTS) were grown from aqueous solution by slow evaporation technique. The grown crystals were subjected to various studies such as FTIR, Powder X-Ray diffraction, second harmonic generation (SHG), UV-visible spectra and thermal analysis (TG-DTA). The FTIR study confirms the incorporation of L- glutamic acid into ZTS crystal. The enhancement of SHG efficiency was observed in doped ZTS crystal. The doped crystals are optically transparent and thermally stable.
