    Abstract:
    Methyl-para-hydroxy benzoate is a potential organic nonlinear optical (NLO) material. The pure and amino acid (glycine) doped MHB crystals are grown by slow evaporation solution growth technique. Single crystal X-ray diffraction studies of both pure and amino acid doped samples are carried out and the results are compared. FTIR studies are performed to identify the presence of various functional groups in the grown crystal. The UV-vis spectra confirm the improvement in the transparency of these crystals on doping amino acid. The amino acid doping improves the NLO properties. The dopant increases the hardness value of the material.
