ABSTRACT: Copper Sulphate single crystals, doped with Glycine were grown using slow evaporation method from an aqueous solution. The prepared crystals were analyzed with UV-visible spectroscopy and FTIR. The UV visible spectrum was utilized to estimate the optical transparency of the grown crystals. The UV spectrum indicated low absorbance in the visible region and high absorbance in the UV region, especially in 200nm to 290nm. The Energy gap (Eg) of crystals was observed to decrease from 3.77 eV to 2.49 eV when 5gm of Glycine was added in a ratio with Copper Sulphate. The FTIR studies confirmed the presence of various functional groups in the prepared crystals.

Key words: Slow evaporation, FTIR, UV, Energy gap, Tauc plot
