Abstract

Direct detection of singlet oxygen (¹O₂) luminescence around 1270 nm is the golden standard of ¹O₂ identification. In this study, the effect of the discrimination threshold on the detection of ¹O₂ luminescence that generated from the photoirradiation of Rose Bengal (RB) was evaluated by using a self-developed photon-counting detection system. The obtained results show that the discrimination threshold for photon counting has a significant impact on the intensity and shape of the measured ¹O₂ luminescence, which resulted in the variation of ¹O₂ lifetimes. The optimal discrimination threshold is determined to be about -0.0412 V, and the corresponding ¹O₂ lifetime in air-saturated distilled water is 4.26±0.06 μs.
