Paper Abstract

The fluorescent spectra of human blood with different concentration induced by different wavelength LED light are reported in this paper. The phenomenon that fluorescence peaks are apparently red-shifted with the increase of blood concentration is analyzed and the mechanism is given a reasonable explanation. The results indicate that the peak is shifted following the rule of e-exponent with the increase of the blood concentration. The mechanism of different energy transfer with different fluorescent areas is analyzed from the theory of energy transfer. The resonance energy transfer is the primary reason of the fluorescent spectra peaks. The concept of the idea fluorescence and the inner fluorescence is also brought forward in this paper. The research will give refer intrinsic fluorescence diagnostic techniques of organic tissue.
