Absolute PL Quantum Yield Measurement System

The C9920-02 and -03 Absolute PL Quantum Yield Measurement System measure the photo-luminescence (PL) quantum yield for photo-luminescent materials using a PL method.
Improvements in the luminous efficiency of photo-luminescent materials themselves are critical when applied to applications in the industrial field. Therefore, there must be an accurate means for measuring the PL quantum yield (the ratio of the number of photons of light radiated from the photo-luminescent materials to the number of photons of light the materials absorbs). The C9920-02 and -03 systems answer this need by measuring absolute values for PL quantum yield. The system is made up of an excitation light source that uses a highly stable xenon lamp, monochromator, an integrating sphere capable of nitrogen gas-flow and a multi-channel spectrometer capable of simultaneously measuring multiple wavelengths.
