摘要

The development of advanced materials for optoelectronic applications remains a persistent challenge, particularly in enhancing nonlinear optical (NLO) efficiency for technological progress and environmental sustainability. This study addresses this by investigating the dual doping of Potassium Hydrogen Phthalate (KUCA) crystals with urea and mediated by Coleus amboinicus to significantly modulate and improve their intrinsic characteristics. The grown KUCA single crystals were cultivated using an aqueous solution growth technique. Their structural features were examined via X-ray diffraction (XRD) analysis, while UV–visible spectroscopy was employed to evaluate linear optical properties, revealing an optical band gap of 4.89 eV. Comprehensive characterization using XRD, FTIR, EDS, and SHG techniques was conducted. Notably, KUCA crystals exhibited a second harmonic generation (SHG) efficiency 2.48 times greater than that of potassium dihydrogen phosphate (KDP), and the implications of these findings were rigorously analyzed. These findings underscore the successful modulation strategy and highlight the potential of these dual-doped KUCA crystals as promising candidates for advanced optoelectronic and frequency conversion devices.
