| Outline of Final Research Achievements |
The photophysical properties of up-conversion based on triplet-triplet annihilation using Pd-octaethylporphyrin and diphenylanthracene were investigated in polyethylene-block-poly(ethylene glycol) micelles. The process of up-conversion was occurred in the polymeric micelles containing sensitizer and emitter through the triplet-triplet energy transfer and triplet-triplet annihilation. Upon excitation at 532 nm in deaerated aqueous solutions they showed weak up-conversion fluorescence, the efficiency of which increased dramatically in the presence of surfactant. The threshold power density between the second order and the first order power dependence of up-conversion fluorescence decreased upon addition of surfactant.
