Fluorescence spectrum characteristic of ethanol--water excimer and mechanism of resonance energy transfer 总被引:1,自引:0,他引:1 下载免费PDF全文
The steady-state fluorescence spectrum characteristic of
ethanol--water excimer has been studied in this paper. By analysing
the features of the sharp emission spectrum with fine structures in a
shortwave band and the characteristics of the broad and featureless
fluorescence peaks in the longwave band, one can conclude that the
excimers are formed between the new ethanol--water cluster molecules
in the excited state and the ground state through the interaction
among different chromophores. The excitation spectra in the two
fluorescence bands have been studied, and their emission mechanisms
have been ascertained
based on the energy transfer theory. Furthermore, the critical distance of
the resonance energy transfer has been calculated. 相似文献
