摘要：

Highly sensitive spectroscopic experimental setup was built to detect infrared luminescence with both time and spectral resolution. In this contribution, phosphorescence of meso-tetra(4-sulphonatophenyl)porphin, which is used as a photosensitizer for photodynamic therapy of cancer, and emission of singlet oxygen were studied. Two-dimensional matrices of data (counts as a function of time and wavelength) were obtained. From these matrices, 1.7 mus lifetime of the photosensitizer triplet state and the same rise-time of the singlet oxygen emission were resolved. Further, 3.7 mus lifetime of singlet oxygen phosphorescence was determined. (C) 2003 Elsevier Science B.V. All rights reserved.
