Patent ID: 7947502

Claim:
A kit for calibration of a photoluminescence measurement system, the kit comprising: (a) a plurality of fluorescence standards (i) comprising at least one of a biphenyl derivate according to the general formula (1) wherein R 1 and R 6 each represent an alkoxy moiety, and the remaining moieties R 2 -R 5 and R 7 -R 10 independently represent a hydrogen or an alkyl moiety, wherein the alkoxy and alkyl moieties independently are cyclic or acyclic, branched or linear; a naphthalene derivate according to the general formula (2) wherein the moieties R 1 to R 8 independently represent a hydrogen or an alkoxy moiety, or partially in combination with each other an anellated, saturated, hetero- or homo-nuclear ring; a 3H-phenoxazin-5-on derivate according to the general formula (5) wherein the moieties R 1 and R 2 independently represent an unsubstituted or a substituted, branched or linear alkyl moiety; a hemicyanin derivate according to the general formula (7) wherein R 1 to R 3 independently represent an unsubstituted or a substituted, branched or linear alkyl moiety, X − an arbitrary anion, and the C atoms designated with an asterisk can be independently bridged by a saturated C5 or C6 ring; a hemicyanin derivate according to the general formula (8) wherein R 1 to R 5 independently represent a hydrogen moiety or an unsubstituted or a substituted, branched or linear alkyl moiety, X − an arbitrary anion, and the C atoms designated with an asterisk independently can be bridged by a saturated C5 or C6 ring; a p-terphenyl according to the general formula (9) wherein R 1 to R 3 independently represent hydrogen, or an alkyl or alkoxy moiety; a 1,3,4-oxadiazol derivate according to the general formula (10) wherein R 1 to R 4 independently represent hydrogen, or an alkyl or alkoxy moiety; and (b) corrected fluorescence spectra (I i ,(λ)) of the fluorescence standards (i) in computer-readable form and/or in a form to be downloaded from an Internet page, wherein the fluorescence standards (i) meet the following criteria: cover a predefined spectral range in such a way that fluorescence bands of the corrected fluorescence spectra (I i (λ)) have in the vis/NIR spectral range with a wavelength less than or equal to 700 nm at least a minimal predefined intensity at their overlapping wavelengths (λ i/i+1 ) of at least 20% of a corresponding maximum band intensity, fluorescence bands have each a half-width of at least 1400 cm −1 and fluorescence bands each have an unstructured band curve without a shoulder and with only one respective maximum in a relevant spectral range at a spectral resolution of 1 nm.
