T1 - Absolute fluorescence measurements > 1000 nm - Setup design, calibration and standards N2 - There is an increasing interest in optical reporters like semiconductor quantum dots and upconversion nanophosphors with emission > 1000 nm for bioanalysis, medical diagnostics, and safety barcodes and hence, in reliable fluorescence measurements in this wavelength region, e.g., for the comparison of material performance and the rational design of new nanomaterials with improved properties. Here, we present the design of an integrating sphere setup for the absolute measurement of emission spectra and quantum yields in the wavelength region of 650 to 1600 nm and its calibration as well as examples for potential fluorescence standards from different reporter classes for the control of the reliability of such measurements.
