Description 941-950
The semi-organic crystals of the amino acid glycine were developed/grownup by the slow evaporation method from an
aqueous 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 the
existence of additive spices which sanctuary the basic crystalline structure of α-glycine. The energy dispersive x-ray analysis
spectrum (EDAX) and scanning electron microscope (SEM) analysis were carried out to confirm the composition of
elements present in the as-grown amino acid glycine crystals and to conclude the surface morphology. The
existence/presence of functional groups and the nature of bonds present in as-grown amino acid glycine crystals were
assigned by Fourier-transform infrared spectroscopy (FTIR) and micro-Raman spectrums. The optical transparency and cutof
wavelength have been predicted and the optical band gap of the ternary ZnO transition metal added crystals was
calculated. The emission property of the crystals was analyzed by using a Photoluminescence study. The electrical
properties of ZnO transition metallic additive added glycine semi-organic crystals were analysed using the impedance
analyzer. The transition metals addition increases the conductivity of the glycine crystal. The dielectric analysis found that
cultivated crystals were potential candidates for NLO applications. Thermal studies have shown that harvested semi-organic
crystals have high thermal stability and high crystallization. The role of additives brings about significant changes in the
physicochemical properties of semi-organic α-glycine crystals for promising applications of NLO.
