A complex for the fluorescence analysis of macro- and microsamples in the near-infrared

摘要

This paper describes the design features and technical parameters of a complex for characterizing the fluorescence parameters of macro- and microsamples in the near-IR region. Along with the standard 90° setup for exciting and recording the fluorescence, a microfluorimetric technique is used. Two types of InGaAs photodiodes are compared, and the features of the measurements are discussed, using as an example the recording of the IR fluorescence spectra of PbS quantum dots.
