  • Method and kit for calibrating a photoluminescence measurement system
    Patent number: 7947502
    Abstract: The invention is directed to a method and a kit for calibrating a photoluminescence measurement system, in particular a fluorescence measurement system. The kit includes a number of fluorescence standards i and their corrected and certified fluorescence spectra Ii(?), whereby the fluorescence standards i are selected, so that their spectrally corrected fluorescence spectra Ii(?) cover a broad spectral range with high intensity. The standards are characterized by large half-widths FWHMi of their bands of at least 1400 cm?1. According to the method of the invention, partial correction functions Fi(?) are generated by forming the quotient of the measured fluorescence spectra Ji(?) and the corresponding corrected fluorescence spectra Ii(?), which are then combined to form a total correction function F(?) for a broad spectral range.
