Sr doped ZnO nanostructure was prepared by chemical precipitation method and it was irradiated by microwave. The X-ray diffraction studies show that the material has hexagonal phase in nature and the unit cell analysis were done. The unit cell properties such as nearest-neighbour bond length, second-nearest neighbour bond length and bond angles were examined and reported. Purity of the nanostructure was confirmed by the energy dispersive X-ray analysis and morphological analysis were carried out by scanning electron microscopy. Urbach energy and band gap were estimated using the optical absorption spectrum. The intensity of the photoluminescence spectrum depends on the doping concentration of Sr..
