Singlet-Oxygen Sensitization by Associates of Methylene Blue with Colloidal Ag2S Quantum Dots Passivated by Thioglycolic Acid

摘要

Luminescence studies of singlet-oxygen photosensitization by methylene blue molecules in various solvents, as well as by hybrid associates of this dye with colloidal Ag2S quantum dots with average sizes of 2.0, 2.4, and 2.7 nm, are performed. The conditions for simultaneous singlet-oxygen photosensitization and detection of the IR luminescence of colloidal Ag2S quantum dots passivated by thioglycolic acid are determined.
