Abstract

Abstract: The nonlinear optical single crystal of L-Isoleucine (0.2%) Doped Ammonium Dihydrogen Phosphate (LIADP) was grown by slow evaporation solution growth techniques. The grown crystal was subjected to single crystal XRD studies to confirm the crystal structure. Fourier transform infrared (FTIR) analysis was carried out to identify the functional groups of the grown crystal. The UV–vis spectrum was carried out and the calculated band gap energy was found to be 3.18 eV. The electrical properties of the grown crystal have been analysed by dielectric constant and dielectric loss with frequency. The Kurtz-Perry powder technique was used to analyse second harmonic generation (SHG) efficiency of the grown crystal. Kurtz-Perry technique revealed that the SHG efficiency of LIADP is 0.8 times greater than reference KDP crystal. Photoluminescence studies can be used to observe the intensity of grown LIADP single crystal.
