In-depth behavioral study of l-Prolinium Trichloroacetate single crystal: An efficient candidate for NLO applications

Abstract

Organic compounds have constantly proved to be a proficient candidate for nonlinear optical (NLO) applications. In this respect an organic amino acid compound i.e. l-Prolinium Trichloroacetate single crystal has been synthesized and grown through slow evaporation solution growth technique. The lattice parameters obtained from single crystal X-ray diffraction were comparable with reported one. The diffraction pattern along the strain present inside the crystal was measured through powder X-ray diffraction technique. Its photoconductivity has also been observed, in which the traits of dark and photon current were recorded over a range of applied voltage. Further, birefringence was performed for the sample in which it was found that the crystal is having negative optical homogeneity character. The thermal transport parameters were calculated through photo-pyroelectric technique. Its resistance toward the laser beam was examined using laser damage threshold technique. The mechanical characteristics of the single crystal were determined on nanoscale using Oliver–Pharr method.
