摘要

Single crystals of the organic compound 1H-benzotriazole salicylic acid (BZTSA) were grown successfully through the slow evaporation solution technique (SEST). As far as we are aware, this is the initial study reporting the synthesis and detailed characterization of BZTSA crystals. The structural parameters of the grown crystal were determined using X-ray diffraction (XRD) analysis. Vibrational modes were identified through Fourier transform infrared (FTIR) spectroscopy. Optical transmittance was measured to be 86%, with a cutoff wavelength of 320 nm and an optical bandgap of 3.5 eV. The positive photoconductive nature of the BZTSA crystal was confirmed through photoconductivity analysis, which demonstrated a higher photocurrent compared to dark current under illumination. Additionally, the dielectric properties of the crystal were investigated by frequency-dependent dielectric measurements, which provided insights into its electrical behavior and material quality. Furthermore, the third-order nonlinear optical (NLO) properties of the BZTSA crystal were examined using the Z-scan technique.
