Accepted: 31 August 2020
A semi-organic L-tyrosine hydrobromide (LTHB) nonlinear optical single crystal has been harvested using slow evaporation solution technique (SEST) at atmospheric conditions. The ingot has under gone for different characterisations to check its appropriateness for device fabrications. The structural conformation and unit cell dimensions have been estimated using powder X-ray diffraction (PXRD) method. The prominent peaks of PXRD have been indexed and it shows that crystal having non-centrosymmetric in nature with nonlinear optical application in second harmonic generation (SHG). Fourier-transform infrared spectroscopy (FTIR) analysis has been employed to characterise as grown crystal to know about the presence of various functional group in it. The crystalline quality and defects during the growth have been inspected by high resolution X-ray diffraction (HRXRD) technique. Optical studies have been carried out using UV–Vis and photoluminescence (PL) analysis. From UV–Vis measurement, we found that the material exhibits lower cut off wavelength with a high transparency window which is suitable for nonlinear optical (NLO) and optoelectronic applications. A detailed discussion of thermo gravimetric (TG) and derivative thermogravimetry (DTG) along with differential scanning calorimetry (DSC) has been presented to know about the thermal behaviour of LTHB crystal. The thermo mechanical analyser (TMA) which is useful to evaluate the coefficient of thermal expansion (CTE) of the grown crystal has been performed. Laser damage threshold (LDT) density has been noticed to check its strength for high intense laser. The optical, structural, thermal and phase matching studies of titled crystal establish the suitability of this material for optoelectronics and NLO device applications.
