A strong, room-temperature, 1.54 μm emission from erbium-implanted at 190 keV into red-emitting porous silicon is demonstrated. Luminescence data showed that the intensity of infrared (IR) emission from Er implanted porous Si annealed at ≤ 650 °C, was a few orders of magnitude stronger than Er implanted quartz produced under identical conditions, and was almost comparable to IR emission from In0.53Ga0.47. As material which is used for commercial light-emitting diodes.
