Figure S1. The fluorescence emission spectrum of Au NCs(black) and the composite nanospheres(red) upon excitation at 500 nm.

Figure S2. The illumination time with UV light the normalized fluorescence intensity of Au NCs (red) and Au NCs-silica composite nanospheres(black). Each point depicted the average measurements of three times. Error bars were calculated based on the standard deviation of three measurements.
