The interest towards the amino organic zinc oxide compounds with water as solvent persuaded to do thisinvestigation. The growth and characterization of single crystals of simplest amino acid, glycine from aqueous solutionin the presence of zinc oxide and co-doped zinc oxide (co-dopant: Na and K) as an additive using slow evaporationtechnique were carried out. The influence of additives in the growth atmosphere enhanced the crystal quality as well astheir properties. Single crystal X-ray diffraction analysis was carried out to determine the lattice parameters of glycinewith ZnO as an additive. EDAX analysis and Powder X-ray diffraction confirmed the presence of additives, whichpreserve the basic crystal structure of the parent compound. The various fundamental functional groups present in thetitle crystal were identified using FTIR spectral assignments. From UV-Vis analysis, increased absorption in the UVregion and optical transmission in the entire visible region were observed. The mechanical strength of the grown crystalswas estimated from Vickers micro hardness testing.
