An exploration of Enhanced Characteristics and Efficiency of dye-doped L-Threonine single crystal

Abstract The improved crystalline characteristics of a crystal doped with 0.5 mol% methylene blue dye was analyzed and compared using several techniques such as SXRD, FTIR, (Spectrum of absorption and Spectrum of optical transmittance), PXRD, and Second Harmonic Generation (SHG). The crystal was prepared using the slow evaporation method. The work hardening coefficient was evaluated for our synthesized crystal, indicating its soft nature. Additionally, we want to achieve similar levels of second harmonic Generation in both pure L-threonine materials and dye-doped crystals. Research on photoluminescence reveals that fully developed crystals have a reduced number of imperfections. Piezoelectric coefficients (d33) were also calculated for the as- grown Pure L-threonine crystal and L-threonine doped with dye Single crystal. The increased LDT value be attributed to the significantly decreased section, confinement, and mechanical stiffness of both the Pure L-threonine and dye-doped L-threonine Single crystal. The etching tests shown that both the as-grown Pure L-threonine crystal and the dye-doped L-threonine Single crystal had a better level of crystalline fineness and a smaller number of defects. These characteristics are essential for their use in nonlinear optics (NLO) applications.
