ABSTRACT: The optically transparent and bulk single crystal of p-Toluidine
p-Toluenesulfonate (PTPT) was grown by slow evaporation technique. The lattice
parameters and crystallinity of the grown crystal were estimated by single
crystal XRD. The optical absorption of the crystal was recorded using the
UV-Vis-NIR spectrophotometer. The optical bandgap and optical constants of the
material were determined by using absorption spectrum. The refractive index of
the grown crystal has been determined using the Brewster angle method. The
dielectric constant and dielectric loss were measured as a function of
frequency and temperature for the grown crystal. Nonlinear optical properties were performed to confirm the SHG
efficiency of the grown crystal. Hence, PTPT is an excellent NLO material with
enhanced SHG efficiency required for important applications in the field of
optoelectronic and photonics. This material exhibits NLO behaviour remarkably
due to its better optical and dielectric properties.
