Second Harmonic Generation Studies on Dyes (Methyl Orange, Methyl Red) Doped Thiourea Barium Chloride (TBC) Crystals for Nonlinear Optical Applications

Analyzing dissymmetric molecules of semi-organic dyes doped thiourea barium chloride (TBC) single crystals for bettering the SHG frequency and utilizing it for NLO devices casting. Dyes doped TBC crystals were germinated using slow vaporization technique and it was transformed into single crystal using vapour diffusion method. Exemplifying the behavior of dyes doped TBC crystals were carried out using characterization techniques such as PXRD was taken to confirm lattice parameters and structure of grown crystals. The optical transmission of dyes doped TBC were characterized by UV–vis spectra. The functional groups of the compounds present in grown crystal were validated through FT-IR analysis. Vickers hardness number with yield strength and stiffness constant was examined using Vicker’s microhardness tester. The NLO and SHG studies were carried out for identifying optical behavior of dyes doped TBC crystals. The obtained results claims the doped TBC exhibit more efficiency than pure one.
