Study of optical, thermal, mechanical, dielectric and nonlinear optical study on nonlinear optical material Bis-(L-Tyrosinato) Cupric acetate single crystals for optoelectronics application

Abstract

The semi-organic nonlinear optical single crystal Bis (L-Tyrosinato) Cupric acetate (BLTC) was synthesized through a slow evaporation process in atmospheric conditions. A single crystal X-ray diffraction analysis of the formed crystal revealed that it is an orthorhombic crystal system with the space group P212121. Additionally, the powder X-ray diffraction patterns and diffracting planes of the BLTC crystal were recorded and identified. Fourier Transform Infrared (FTIR) spectroscopy analysis was used to characterize the formed crystals in order to identify the various vibrational modes caused by the different functional groups present in BLTC. The 1H and 13C NMR spectra were used to examine the crystal’s hydrogen and carbon environments. The UV-visible, near-infrared, and photoluminescence (PL) analyses have been used to do optical studies. According to our findings, the material has a decreased cut-off wavelength and a high transparency window, making it suitable for nonlinear optical (NLO) and optoelectronic applications. The BLTC crystal’s predicted band gap was found to be 4.1 eV. Thermo gravimetric (TG) and differential thermal analysis (DTA) techniques were used to determine the thermal properties of BLTC. With three different frequencies, the dielectric measurement of the crystal was observed with respect to temperature. An analysis has been done on the harvested crystals mechanical characteristics. In the developed BLTC crystal, morphological changes on the surface are seen. The material’s second harmonic generation (SHG) was tested using the Kurtz and Perry powder method, and it was found to be higher than the KDP.
