METHOD FOR MEASURING FLUORESCENCE ON SUBMICRON-SCALE GRAIN SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring fluorescence on submicron-scale grain surfaces, simple but high in detection accuracy. SOLUTION: The method for use in measuring fluorescence in a suspension of submicron-scale grains retaining a fluorescent substance is characterized in that a difference that is great enough to avoid the effect of scattering is provided between the excitation light wavelength and the fluorescence wave length for the detection of fluorescence.
