Fluorescence effect of ion-implanted sapphire doped with Ag/Cu/Fe elements

The fluorescence effect and microstructure of the nanocomposite samples prepared by ion implantation have been studied in the subsurface area. Based on the UV–vis and VUV data, the luminescence properties of implanted samples have been presented and discussed. The research indicates that the surface plasma resonance has an impact on the fluorescence effect notably. In addition, the fluorescence performance of the substrates implanted with ions is related to the outermost electron number of the injection element. And SRIM is used to analyze the energy loss in the process of ion implantation.
