Abstract: 
Copper Tartrate crystals were grown by Gel Growth technique by single diffusion method. Silica gel of Optimum specific gravity was set with tartaric acid at optimum pH and aging period. Band gap of copper tartrate crystal is determined using to be 5.24 eV. In PL spectra broad peak is observed at nearly 367.44186 nm in the range 287 nm to 458 nm along with the sharp, intense transmission maxima peak at wavelength nearly 505.03876 nm which is characteristic of a material composition and electronic band structure. This shows the transparency of it in UV-Visible region and it as a filter in this range TGA analysis concludes that Copper tartrate has loss of one-half water molecule as crystalline water and is stable up to 85.02 ℃DSC analysis assigns the temperature value 314.5 ℃ as melting point and apparent enthalpy of fusion determined is 10.18 mW.
