The Horiba Fluorolog-3 spectrofluorometer is used for steady-state and time-resolved phosphorence measurements of solid, liquid, and thin film samples in the 200nm to 1050nm spectral range. The instrument has automated polarizers for anisotropy measurements, a Peltier-temperature-controlled sample chamber, a 4-position motorized sample chamber, and an integrating sphere for Quantum Yield measurements.
