Absolute PL quantum yield spectrometer


The C9920-02G;Absolute quantum yield spectrometer employs the PL (photoluminescence) method to measure absolute quantum yields quick and accurately.
Their setup comprises an excitation light source, monochromator, an integrating sphere capable of nitrogen gas flow and a CCD spectrometer for detecting the whole spectral range simultaneously. The dedicated software keeps operation easy. Two sample holders are available for thin films, powders and cuvettes holding liquid samples. This allows for the use of the C9920-02G system in various fields like industry, biological and academic research.
