Abstract: | A new single crystal of cesium sulphate-doped 4-methoxyaniline (CS-4MOA) was obtained by the solvent evaporation approach. XRD manifests that the CS-4MOA crystallizes in orthorhombic crystal structure. The existence of several functional groups in the CS-4MOA crystal is affirmed by FTIR analysis. SEM-EDAX analysis was performed to examine the surface morphology and the composition of CS-4MOA sample. Ultraviolet–visible spectral study validates the transparency of CS-4MOA in the region of 330–1100 nm. The thermal steadiness of the CS-4MOA crystal was examined using TG/DTA, which revealed that it was stable up to 88 °C. The mechanical stability of CS-4MOA crystal was assessed through Vickers microhardness analysis. VSM analysis was used to evaluate the magnetic behaviour of the CS-4MOA crystal. The electrical characteristics of the CS-4MOA were investigated by impedance study for various temperatures. The NLO parameters of CS-4MOA were computed by Z-scan technique. The existence of second order nonlinear optical susceptibility in CS-4MOA was confirmed by the SHG investigation. Additionally, antimicrobial activity of CS-4MOA was performed against bacterial strains and fungal pathogen for medicinal applications. |
