Focusing Photoluminescence Properties of Bis Thiourea Cadmium Acetate Crystal Exploiting Organic Ligand of Oxalic Acid for NLO Device Applications

Modifying optical properties of crystal is very fundamental need for designing various photonic devices hence in current investigation the oxalic acid (OA) has been firstly doped in Bis thiourea cadmium acetate (BTCA) crystal with aim to optimize the luminescence properties of BTCA crystal. The crystals have been grown by slow solvent evaporation technique at 35?C. The structural parameters of grown crystals have been determined using the single crystal X - ray diffraction technique. The incorporation of OA in BTCA crystal matrix has been confirmed by Fourier transform infrared analysis. The color centered luminescence studies have been carried out which established the prominent red shift in peak maxima of emission wavelength of BTCA crystal due to doping of OA.
