Nitrogen-doped silicon nanowires were obtained via a high temperature oxide assisted method. Both their cathodoluminescence and photoluminescence exhibited blue emissions, which might attributed to the nitrogen doping. Both the elemental mapping analysis and smooth cathodoluminescence image suggested uniform nitrogen doping in the silicon nanowires.
