Abstract :

This paper deals with the growth and characterization of undoped and picric acid doped glycine lithium sulphate crystals. Growth of the crystals was carried out by solution method with slow evaporation technique. Solubility studies were carried out for the samples at various temperatures ranging from 30 oC to 50 oC. XRD studies reveal the structural properties. The functional groups of the sample were identified by FTIR studies and the optical band gap was calculated using the transmission spectra. The microhardnes characterization was performed for samples to understand the mechanical strength. Nonlinear optical activity for the grown crystals has been checked by carrying out second harmonic generation (SHG) studies.
