The invention belongs to the technical field of chemical catalysis, and discloses a photosensitizer with high singlet oxygen yield, and the photosensitizer is an inorganic-organic hybrid system composed of cadmium selenide quantum dots and triplet acceptor molecules anchored on the surfaces of the cadmium selenide quantum dots. The cadmium selenide quantum dots are used as sensitizers to construct an inorganic-organic hybrid system with triplet receptor molecules, the singlet oxygen generation rate of the cadmium selenide quantum dots is nearly 4 times that of single CdSe QDs, and the cadmium selenide quantum dots have great application prospects in the aspects of photocatalysis and photodynamic therapy. 本发明属于化学催化技术领域，公开了一种具有高单线态氧产率的光敏剂，该光敏剂是由硒化镉量子点和锚定在硒化镉量子点表面的三线态受体分子构成的无机-有机杂化体系。本发明以硒化镉量子点为敏化剂，与三线态受体分子构建无机-有机杂化体系，其单线态氧产生速率是单独CdSe QDs的近4倍，在光催化和光动力治疗方面具有极大应用前景。
