Synthesis and characterization of pure and L-proline doped copper sulphate single crystals

Proficient semi-organic non linear optical pure and 0.01 wt% l-Proline doped Copper Sulphate (CS) pentahydrate single crystals with molecular formula CuSO(4 center dot)5H(2)O were synthesized by the process of slow evaporation technique using de-ionized water as the solvent. Powder X-ray diffraction analysis revealed that the grown crystals belong to triclinic system. The various functional groups were identified by the Fourier transform infrared (FTIR) spectroscopy. The optical quality of the single crystals and band gap energy were found out by the UV-Vis NIR spectral analysis and the refractive index of the material has been deliberated. The thermal stability of the single crystals was analyzed by thermo gravimetric (TG) and differential thermal analyses (DTA). The kinetic parameters have been determined from TGA data. The dielectric response of the synthesized crystals was studied by dielectric studies. The mechanical stability of the grown crystals was examined using Vicker's hardness tester. The second order nonlinear optical properties of the crystals were determined using Q switched High Energy Nd: YAG Laser. The pure and doped crystals yield sufficient opposition to laser beam with threshold values 26.697 GW/cm(2) and 22.652 GW/cm(2).
