Overview

The PerkinElmer FL 8500 is a spectrofluorometer that combines a pulsed xenon lamp with a dual-monochromator optical design for sensitive fluorescence measurements over a wide wavelength range. It supports excitation, emission and synchronous scans; three-dimensional fluorescence maps as excitation-emission matrices (EEM); time-based intensity measurements; and a phosphorescence mode. Cuvette, solid-sample and powder holders accommodate solutions, films, glasses, powders and ceramics, and an integrating sphere allows absolute quantum yield to be determined. The system is used in the development of luminescent materials such as quantum dots, perovskites, phosphors and organic emitters, in studies of fluorescent dyes and biomolecules, in detecting fluorescent impurities in water and food, and in spectral fingerprint comparison for quality control, with software for spectral correction, peak analysis and quantitative calibration.
