| 摘 要： | 用正电子素Ｏ－Ｐｓ研究心亚甲兰为光敏剂在甲醇和水体系中激光诱导单态氧＾１Ｏ２的形成，理论推导了一Ｏ－Ｐｓ湮没率的改变与亚甲兰浓度之间的关系，经与实验结果对照证实了单态氧的产生。 |
| 关 键 词： | 正电子素 激光诱导 单态氧 光敏剂 亚甲兰 |

| Abstract: | The singlet oxygen O induced by laser in a methanol- water system with photosensitizer, methylene blue (MB), was probed by positronium. According to the theory of positron annihilation and chemical reaction kinetics , the relation between concentration of MB and variation of positron annihilation rate caused by , was deduced. The experimental results agree with the theory, confirming the formation of 1O2 in such a photochemical reaction. |
| Keywords: | Positronium Laser inducement Singlet oxygen Photosensitizer Methylene blue |
