Influence of l-lysine on optical and dielectric traits of cadmium thiourea acetate complex crystal

Crystals enduring strong thiourea-metal coordinated ligand demonstrate outstanding combination of dielectric and optical properties which are exclusively desirable for nonlinear optical (NLO) device applications and thus current study has been designed to investigate the semiorganic cadmium thiourea acetate (CTA) complex crystal. The pure and l-lysine (LL) influenced CTA complex crystals have been grown by commercial slow solvent evaporation technique at room temperature. The structural parameters of grown crystals have been experimentally determined by means of single crystal X-ray diffraction technique. The UV-vis spectral analysis has been employed within the wavelength range of 200-1100 nm to examine the effect of LL on optical transparency and extinction coefficient of CTA crystal. The enhancing effect of organic ligand of LL on second harmonic generation (SHG) efficiency of CTA complex crystal has been discussed and the SHG efficiency has been determined by employing the Kurtz-Perry powder test. The reliance of dielectric constant and dielectric loss of pure and LL influenced CTA crystal on temperature has been examined within the range of 35-90 °C. The compatibility of LL doped CTA crystal for distinct technological device applications have been explored.
