在室温下，在有机溶剂中，观察到多孔硅通过能量转移产生的单线态氧的光致发光。通过光致发光激发光谱得到了能量转移间接激发的证据。激发光谱表明，通过使用多孔硅作为光敏剂，可以利用整个可见光范围的光在室温下产生单线态氧。
Photoluminescence (PL) from singlet oxygen generated by energy transfer from porous Si is observed at room temperature in an organic solvent. The evidence of the indirect excitation by energy transfer is obtained from PL excitation spectroscopy. The excitation spectrum indicates that by using porous Si as a photosensitizer, light of the entire visible range can be utilized for singlet oxygen generation at room temperature.
