Distance Dependence of Gold-Enhanced Upconversion luminescence in Au/SiO2/Y2O3:Yb3+, Er3+ Nanoparticles
We report a localized surface plasmon enhanced upconversion luminescence in Au/SiO2/Y2O3:Yb3+,Er3+ nanoparticles when excited at 980 nm. By adjusting the silica spacer's thickness, a maximum 9.59-fold enhancement of the green emission was obtained. Effect of the spacer distance on the Au-Y2O3:Y...
