title: Synthesis growth and characterization of L-Valinium Picrate a new nonlinear optical crystal.
abstract: New nonlinear optical (NLO) single crystal of L-Valinium Picrate (LVP) was grown by slow evaporation solution growth technique at room temperature. The cell parameters of the grown crystal were estimated by single crystal X-ray diffraction analysis. The presence of functional groups was identified from Fourier transform infrared spectrum. The transmission and absorption spectra of this crystal show that the lower cut-off wavelength lies at 380 nm. Thermal analysis was performed to study the thermal stability of the grown crystal. The powder second harmonic generation efficiency of the grown crystal measured by Kurtz technique is 2 times efficient of Potassium dihydrogen orthophosphate (KDP).
