FP-8000 Series - Integrating Spheres & Fluorescence Quantum Yield

Fluorescence Quantum Yield

Fluorescence Quantum Yield measurements provide information about the efficiency of a molecule’s fluorescence and is defined as the ratio of the number of photons absorbed to the number of photons emitted by a sample. Different molecular and environmental conditions not only effect whether a molecule will fluoresce or not, but can also determine the intensity of the emitted fluorescence radiation. Fluorescence quantum yield is measured using an integrating sphere to ensure that all sample fluorescence is collected.
