| 摘 要： | 从实验的角度研究了HA光敏剂激发态的敏化特性，建立了单态氧量子产率在近红外区的荧光光谱测量系统，测定了HA光敏剂的单态氧量子产率为0．78。结果表明，该类光敏剂具有较强的敏化效应，是一类有前途的光动力治疗(PDT)候选光敏剂。

| Abstract: | The equipment of measuring fluorescence spectrum in near infrared and quantum yield for singlet molecule oxygen produced by photosensitization is developed. The emission spectra from singlet molecule oxygen in the excited state, ?g, photosensitized by HA in organic solvents are obtained on the equipment. The spectroscopic technology for 1 measuring singlet oxygen fluorescence in near about 1270nm is an advantageous and reliable method for measurement of quantum yield of singlet oxygen sensitized by photosensitizer Hyporcrellin A. |
