| Research Abstract |
The active oxygen species, singlet oxygen, was generated by high power green-LED photoexcitation of Rose Bengal. Portable ESR spectrometer, a Charge integrating amplifier operated at Low Temperature for Near-Infrared low-level light were developed. The signal-intensity of singlet oxygen generated by 5W LED irradiation was as strong as 10^<-13>W emission by an InGaAs LED. We estimated that 6.4.×10^<11> molecules of the singlet oxygen. We estimated that 2.4×10^<20> molecules of the radical were generated from the Rose Bengal photoexcitation. The part standard action of main active oxygen was made explicit by this study.
