(a) Emission spectra of upconversion NCs on glass slide before and after gold sputtering excited with a 980 nm diode laser at the power density of 11 mW/cm2, 40 mW/cm2 and 67 mW/cm2 for (1), (2) and (3) respectively. (b) Power dependent upconversion emission before (open) and after (solid) gold sputtering. (c) Power dependent enhancement factor of upconversion emission on glass slide at different wavelengths.
