Investigation on optical behavior of L-cystine dihydrobromide for optoelectronic Applications.

In present investigation L-cystine dihydrobromide (LCD) crystal has been grown by slow evaporation technique at room temperature. The optical studies were carried to examine optical transparency and determine the optical constants of the grown crystal quenching the optoelectronics applications. The optical studies ascertained high optical transparency and cut off wavelength was found to be 265 nm imperative for nonlinear applications. The optical band gap of grown crystal was found to be 5.16eV. The optical constants, extinction coefficient, nonlinear index of refraction, optical conductivity, complex dielectric, optical band gap, reflectance were determined to scrutinize the electronic band structure highly demanded for optoelectronics applications.
