Paper Abstract

Native fluorescence spectral characteristics of red blood cells were studied in the visible region in this paper. Blood samples were collected from normal small albino rats. Native fluorescence spectra of the erythrocyte were induced using Light Emitting Diode (LED) at yellow wavelength about 570+/- 16 nm ((Delta) (lambda) 0.5approximately equals 32nm). As the rat's erythrocyte content of in physiological water is increasing, the fluorescent primary emission peak is red shifted from 588 nm to above 615 nm. Furthermore, the fluorescence intensity at about 600 nm was found to be maximal while the rat's erythrocyte consistence is 1%. Moreover, it is shown in large numbers of experiments that LED-induced fluorescence spectra of the erythrocyte are similar with the whole blood. It may make sense for low- intensity light therapy.
