摘要: The upconversion luminescence (UCL) enhancement based on the surface plasmonic resonance (SPR) of noble metals is a promising way to improve UCL efficiency. However, it still challenge achieve stable and effective enhancement. Here, we present preparation porous Ag/YVO4:Yb(3+), Er(3+) composite film via simple double annealing method. It exciting observe that maximum 36-fold ((2)H11/2-(4)I15/2) 30-fold ((4)S3/2-(4)I15/2) in film, attributed coupling between SPR excitation light by adjusting peak wavelength, controlling distance improving scattering-absorption ratio. Furthermore, factor strongly depended power concentration.
