Abstract:
Cadmium doped copper tartrate crystals were grown by Gel Growth technique by single diffusion. Silica gel of optimum specific gravity was set with tartaric acid at optimum pH and aging period for crystal growth. Band gap of cadmium doped copper tartrate crystal is determined using Ultraviolet-Visible Spectroscopy is 5.780 eV. Blue Color of cadmium Copper tartrate crystal and transparency is confirmed using Photoluminescence spectroscopy. Emission originates from Cu2+ vacancy-related defects or their complexes. Dimensions of crystals are found from Powder X-Ray Diffraction data. The edge lengths of unit cell calculated from indexing of PXRD data are, a = 5.47 Å, b =11.76 Å, c =9.20Å and volume of unit cell is, 621.02208 Å3.
