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.

活性氧物种，单线态氧，产生高功率绿光LED光激发的玫瑰红。研制了一种低温电荷积分放大器，用于近红外弱光的便携式ESR谱仪。由5W LED照射产生的单线态氧的信号强度与<-13>由InGaAs LED发射的10^ W的信号强度一样强。我们估计有6.4 ×10^<11>分子的单线态氧。我们估计，2.4×10^<20>分子的自由基是由虎红光激发产生的。本研究明确了主要活性氧的部分标准作用。
