Abstract

We report theory and measurements of a simple and absolute technique for the determination of the total emitted spectral fluorescence yield inside an integrating sphere from the sphere coating under irradiation with a monochromatic beam. This technique measures the spectral response to the radiation exiting from an integrating sphere under irradiation by a spectrometer-detector system. The total spectral fluorescence yield can be calculated by the response measurement and an overall responsivity function that is obtained by calibrating the system with a standard source. This technique provides quantitative fluorescence analysis of the coating of an integrating sphere wall.
