Description
Summary:Thiourea potassium hydrogen phthalate (TKHP), a semiorganic nonlinear optical single crystal is grown by slow evaporation solution growth technique at room temperature. FTIR and NMR spectral studies of the grown crystal confirm the chemical composition and their corresponding functional groups. UV–visible NIR spectral study confirms the transmission band of 100% in the range 200–900 nm with enhanced lower cutoff wavelength. The Single crystal XRD reveals that the grown crystal is an orthorhombic system. Thermal stability of TKHP was found to be 305.1 °C. The second harmonic generation (SHG) efficiency of TKHP is observed by the Kurtz powder technique. [Display omitted] •Thiourea potassium hydrogen phthalate crystal grown by slow evaporation method.•Crystal has transparent close to 100% and has a lower cutoff wavelength 290 nm.•SHG efficiency of crystal is superior than KDP crystal.•TKHP crystal showed thermal stability 305.1 °C.•Results show that TKHP crystal is suitable for optoelectronic applications.
