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 cut-of 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.

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 cut-of 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.
