Optical, photoconductivity and dielectric studies of zinc sulphate added glycine crystal for photonics applications

In present studies, we have successfully grown γ-glycine single crystal in the presence of ZnSO4 as an additive by using slow solvent evaporation method. Powder X-ray Diffraction study confirms crystal grown in γ-phase and it crystallizes into a hexagonal structure with a space group of P31. UV-vis transmittance spectra was recorded for the sample to analyse the optical transparency in visible and near infrared region (NIR). In Kurtz-Perry powder test, SHG efficiency of the grown ZnSO4 added glycine crystal is found to be 3.18 times higher than reference KDP crystal. The dielectric constant and dielectric loss of ZnSO4 added glycine crystal was carried out as a function of temperature by varying the frequency and the obtained results were discussed. The photoconductivity study confirms the positive photoconducting nature of grown ZnSO4 added glycine crystal.
