Z-scan, antibacterial activity and photocatalytic studies of sodium bromide-doped L-alanine single crystals

The slow evaporation method was used to produce sodium bromide-doped L-alanine (SBLA) single crystals at room temperature. Advanced techniques including dielectric, cyclic voltammetry (CV), Vickers microhardness, impedance, Energy-dispersive X-ray spectroscopy (EDAX), Scanning electron microscope (SEM), Photocatalytic activity test, ultrasonic study, Z-scan, laser damage threshold (LDT) and antibacterial activity studies were used to investigate the grown SBLA crystal. To determine the SBLA crystal's specific capacitance value, a CV research was conducted. The SBLA crystal's stiffness constant, yield strength, work hardening coefficient, and hardness were all assessed using Vickers microhardness testing.The structure of the produced single crystals, which resemble flowers, was examined using a scanning electron microscope (SEM). To determine the percentage amount of the elements in the SBLA sample, an EDX analysis was conducted. The dielectric loss and dielectric constant of the SBLA crystal have been ascertained using a dielectric investigation.The Nyquist diagram of the sodium bromide-doped L-alanine single crystal value of the bulk resistance and grain boundary resistance are found by impedance analysis. The density, velocity, compressibility and bulk modulus values of the aqueous solution of SBLA crystal were evaluated by ultrasonic interferometer analysis. The photocatalytic activity SBLA sample was tested to check the dye removal in congo red and methylene blue dyes. The SBLA crystal’s nonlinear refractive index (n2) and nonlinear absorption coefficient (b), and also third-order nonlinear optical susceptibility (χ(3)) values were determined by investigation of Z-scan. The antibacterial activity and LDT studies were also carried out for sodium bromide-doped L-alanine (SBLA) crystal and the results are analyzed.
