| Abstract | ||
A new NLO crystal L-Threonine doped Potassium Bromide (LTPB) crystal is reported by synthesis and growth along with the comparison of pure L-Threonine. Grown crystals of LTPB crystals are characterized with UV-Vis-NIR, FTIR, Powder XRD, TG-DSC, and SHG. Clear crystals of very good transparency were harvested by slow evaporation technique at room temperature. Inclusion is confirmed with the change in the structure of materials using Xrd pattern. FTIR spectrum exposes the available functional groups in the grown crystal to confirm the new arrival. TG-DSC spectra show the thermal properties of LTPB found that the thermal stability extends up to 750°C. The basic optical behavior of the grown crystal was examined using absorption and transmittance spectra obtained from UV-Vis-NIR spectra. The efficiency of SHG of the LTPB crystal was recorded using Kurtz powder method. |
