Effect of L-Valine on the Growth and Characterization of Potassium Bromide Crystal

Nonlinear optical single crystals of L-Valine doped Potassium Bromide (LVPB) were grown by synthesization of KBr doped with L-Valine by dissolving it with the solvent as water. At room temperature, good optical crystals of clear transparency were harvested by solution growth slow evaporation technique. Using a computer program, powder XRD analysis confirms the grown crystal from the calculation of 2theta and hkl values. Available functional groups in the LVPB grown crystal was exposed by FTIR analysis which confirms the inclusion of L-Valine. The thermal stability of grown LVPB was found to be noted as 225°C from the TGA-DSC studies. The absorption and transmission spectra of UV-Vis-NIR reveal the optical transparency of the crystal which leads to an idea to fabricate the optical devices.
