SYNTHESIS AND CHARACTERIZATION OF LANTHANUM CHLORIDE DOPED L-ARGININE HYDROCHLORIDE SINGLE CRYSTAL: FOR OPTOELECTRONICS APPLICATIONS

Abstract

Amino acid derivative crystals exhibit good nonlinear and electroptics properties. L-arginine hydrochloride doped by lanthanum chloride single crystals were successfully synthesized and grown by using slow evaporation solution growth method at room temperature.  The single crystal XRD analysis revealed that both 1 and 2 mol% LaCl₃ doped LAHCl crystals were crystallized monoclinic system with P2₁ space group. The EDX result confirmed that the presence lanthanum and chloride in LAHCl crystal. The UV-Vis-NIR spectral studies revealed that the crystals were transparent in the wavelength rage between 235-1100 nm and the band gap energy of pure and doped samples is found to be 5.27 eV. The SHG efficiency of the grown crystals confirmed that the NLO behavior of green color emission to offer frequency doubling process for optoelectronics application
