The Photoinduced afterglow of singlet oxygen was found in air saturated solutions of protoporphyrin and naphtacene in carbon tetrachloride. The excitation spectra coincide with the absorption spectra of the pigments. The lifetime is near to 7 msec, the quantum yield--to 3-10(-5). The emission maximum lies at 1270 nm. The data suggest that the luminescence is generated by oxygen in the 1 delta g state produced by the energy transfer from triplet molecules of the pigments to O2.
在原卟啉和并四苯的四氯化碳空气饱和溶液中发现了单线态氧的光致余辉。激发光谱与色素的吸收光谱一致。寿命接近7毫秒，量子产率为3×10⁻⁵。发射最大值位于1270纳米处。数据表明，发光是由色素三重态分子向O₂的能量转移产生的¹Δg态氧所产生的。
