Investigation on optical, thermal and photoconductivity behavior of sodium hydrogen l-cysteine monohydrate


In present investigation Sodium Hydrogen L-cysteine Monohydrate (SHCM) 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 328 nm imperative for nonlinear applications. The optical band gap of grown crystal was found to be 5.05eV. The optical constants, extinction coefficient, nonlinear index of refraction, optical conductivity, complex dielectric, optical band gap were determined to scrutinize the electronic band structure highly demanded for optoelectronics applications. The thermogravimetric analysis (TGA) confirmed the grown crystal was stable up to 249 °C.
