文摘Timefluorescence decays were first performed on hematoporphyrin derivative laser No.3 in buffer at different micelles concentration.The flu.orescence lifetime constants,measured with a time-correlated single photon counting system;could be fitted by two or three exponential components with different relative peak amplitudes depending on the observation wavelength^thus indicating the presence of different emitting molecular species and/or of molecular species in different aggregational states.
