摘要	Fluorescence properties of light-harvesting complex (LHC II) in photosystem II isolated from spinach (Spinacia oleracea L.) was investigated with the time-resolved fluorescence spectroscopic technique. The sample was excited by double frequency Ti: Al2O3 laser with 400 nm wavelength and 120 fs width. Fluorescence signal was detected by Boxcar. Three life-time components (320 fs,4.0 ps and 20.0 ps) were obtained by multi-exponential curve model and nonlinear least-square fitting method. Three fluorescence peaks (652 nm, 672 nm, 691 nm) were obtained by Global analysis and Gauss curve fitting. These components were analyzed according to the structural and fluorescence spectroscopic property of LHC II. The fluorescence ratio of each component to that of all the component was 3.4%, 50% and 46.6% respectively. The possible model of energy transfer in LHC II was discussed.
