Synthesis XRD TEM and Optical Absorption Spectroscopic Characterization of Copper Doped Nano Apatite

Synthesized copper doped chloro-apatite has been characterized by XRD, TEM, Optical and NIR spectroscopy. XRD pattern indicates that the compound shows hexagonal structure with lattice constants of a = b = 9.027 A and c = 13.767 A. TEM images suggest that nano crystals are closely joined together and form agglomerates with rod in shape and are parallel. The optical spectrum exhibits a number of electronic bands due to presence of Cu(II) ions in the compound. The bands in NIR spectra are due to the overtones and combinations of water and phosphate molecules. - (4). The incorporation of foreign cations in the apatite lattice is expected to change the bulk properties. The structures of a number of synthetic substituted apatites are investigated to evaluate the structural changes associated with the substitution (5). The influence of transition metal ions in the host lattice plays an important role in the understanding of the structural variations. In the present work, the preparation and the spectral properties of nano crystals of Cu doped chloro-apatite is studied using XRD, TEM and Optical absorption spectroscopy.
