Structures containing stacked layers of silicon-rich silicon nitride (green-blue luminescence) and oxide (red luminescence) fabricated by ion implantation are reported, and it is shown how a Si-based material can be engineered to emit over a broad range. To study in depth the emission from implanted SiNx matrices, single nitride layers have been also fabricated by the first time. Si excess variation and the relative thickness of nitride and oxide provide the intensity and position variation of the peaks, and thus open the way to engineer a stack with desired emission properties over the whole visible spectrum.
