Indian journal of pure & applied physics (IJPAP)Summary: The semi-organic crystals of the amino acid glycine were developed/grownup by the slow evaporation method from anaqueous solution in the manifestation/presence of zinc oxide and an additive Mn, Fe, Co, Ni, and Pb transition metals.Powder X-ray diffraction and elementary analyses of as-grown amino acid glycine crystals established/confirmed theexistence of additive spices which sanctuary the basic crystalline structure of α-glycine. The energy dispersive x-ray analysisspectrum (EDAX) and scanning electron microscope (SEM) analysis were carried out to confirm the composition ofelements present in the as-grown amino acid glycine crystals and to conclude the surface morphology. Theexistence/presence of functional groups and the nature of bonds present in as-grown amino acid glycine crystals wereassigned by Fourier-transform infrared spectroscopy (FTIR) and micro-Raman spectrums. The optical transparency and cutofwavelength have been predicted and the optical band gap of the ternary ZnO transition metal added crystals wascalculated. The emission property of the crystals was analyzed by using a Photoluminescence study. The electricalproperties of ZnO transition metallic additive added glycine semi-organic crystals were analysed using the impedanceanalyzer. The transition metals addition increases the conductivity of the glycine crystal. The dielectric analysis found thatcultivated crystals were potential candidates for NLO applications. Thermal studies have shown that harvested semi-organiccrystals have high thermal stability and high crystallization. The role of additives brings about significant changes in thephysicochemical properties of semi-organic α-glycine crystals for promising applications of NLO.
