摘要：

The spectral behaviour, lifetime and fluorescence quantum yield of N,N-ditridecyl-3,4:9,10-perylenetetracarboxylic diimide (DTPD) have been measured in chloromethane solvents, such as methylene chloride, chloroform and carbon tetrachloride. The excitation energy transfer to DTPD has been studied to improve the laser emission of DTPD. The value of energy transfer rate constant (K-ET) and critical transfer distance (R-o) indicate a Forster type energy transfer mechanism. The photodecomposition of DTPD in chloromethane solvents has been also studied. (C) 2000 Elsevier Science B.V. All rights reserved.
