    Abstract: PROBLEM TO BE SOLVED: To remarkably reduce a dependency with respect to a wavelength of fluorescent excitation light, and to change the fluorescent excitation maximum of a fluorescence emission group. SOLUTION: A detecting medium containing the fluorescence emission group or a precursor of the fluorescence emission group is mixed with an absorber having an absorption spectrum overlapped with a fluorescent excitation range of the fluorescence emission group. A system generated in the detecting medium and comprising the fluorescence emission group and the absorber has a changed effective fluorescent excitation range accompanied with the changed fluorescent excitation maximum. Irradiation by the fluorescent excitation light is executed within the range of the changed excitation maximum. A measured signal obtained from fluorescence emission measurement indicates only the low dependency with respect to the wavelength of the excitation light. Further, an inexpensive light source such as UV LEDs may be usable because of the changed wave length of the excitation light. COPYRIGHT: (C)2007,JPO&INPIT
