Abstract


Organic materials have outstanding upturn striking high nonlinear optical properties. One such NLO material of good quality single crystal of protonated Piperazinium bis (Salicylate) (PSL) was synthesized by slow solvent evaporation solution growth technique. XRD studies analyzed that the PSL crystallize monoclinic system with space group P21/n. FTIR spectral analysis ascertained the frequencies of various functional groups present in PSL crystal. The optical transmittance and optical band gap were explored from the optical transmission phenomena of PSL crystal. PL studies revealed that prominent emission at 410 nm, when PSL was excited at 320 nm. The mechanically soft nature of the crystal was divulged by Vickers hardness measurement. The LDT value of PSL crystal was estimated as 2.65 GW/cm2. The third order NLO properties of PSL crystal was ascertained by Z-scan studies.
