摘要：
Room-temperature photoluminescence of porous hydrogenated amorphous silicon-carbon alloys (a- Si1-xCx : H) has been studied for different carbon concentrations. Porous a- Si1-xCx : H luminesces at energies much higher than the bulk material. Secondary ion mass spectroscopy reveals that the carbon content is higher in the porous layer than in the starting material, which accounts for the blueshifting of the luminescence into the visible range.
