The Raman signal enhancement factor (EF) of acephate by the substrate of ZnO/NAC/AgNPs can be reached 4.95 × 106. The ultraviolet-visible spectroscopy (UV-vis), high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), zeta potential, Fourier transform infrared spectra (FT-IR) and thermogravimetric analysis (TGA) were used to characterize the substrate of ZnO/NAC/AgNPs. The mechanism of electromagnetic enhancement (EM) assisted by chemical enhancement (CM) was elucidated in detail. The optimal experimental conditions were selected. The interference experiments showed that this method had high selectivity in complex substrates.

Linear optical analysis revealed distinct Urbach energies of 1.14 eV and 0.27 eV for the PVD-grown and RF-sputtered films, respectively, indicating higher defect density in the former. Photoluminescence (PL) measurements showed broader and stronger visible emission for the RF-sputtered film, while the PVD-grown film exhibited narrower near-band-edge emission. Femtosecond transient absorption spectroscopy further revealed that the PVD-grown film featured broad excited-state absorption and faster decay dynamics, whereas the RF-sputtered film displayed ground-state bleaching and longer lifetimes, consistent with fewer traps and reduced carrier loss. Open-aperture Z-scan analysis under 532 nm, 4 ns excitation indicated intensity-dependent NA dominated by defect-assisted processes. The effective nonlinear coefficients from the defect-saturation model were over an order of magnitude higher than those from the Sheik–Bahae model. The RF-sputtered film exhibited shallower defect states that enhanced sequential two-photon and free-carrier absorption, while the PVD-grown film showed early saturation due to localized-state filling.

Meanwhile, the appropriate combination of dual luminescence centers for Er3+ and Tm3+ can easily achieve color-tunable emission including white emission by adjusting the content of doped ions upon 980 nm excitation.
