Paper Abstract

Phosphorescence and fluorescence spectra of human breast tissues excited at two wavelengths were measured and compared at low temperature. A blue shift of fluorescence spectral peak was observed at low temperature for the excitation wavelength at 300 or 340 nm. The phosphorescence spectra excited at 300 nm were found to be centered at 412 nm while the fluorescence spectra consisted of two bands located at about 340 nm and 440 nm. For 340 nm excitation, the phosphorescence spectral profile was found to be relatively smooth but shifted to the red centered at 480 nm while the fluorescence consisted of two bands at 375 nm and 440 nm.
