摘要
Among the various chiroptical spectroscopic techniques available today, circularly polarized luminescence (CPL) plays a minor role and is still used by a limited number of specialists The cost of the few commercial instruments available and the complexity of homemade apparatuses have strongly limited the widespread application of this technique New technological approaches, such as the use of light emitting diode (LED) sources, may significantly simplify the required instrumentation and encourage new potential users Calibration procedure and the quantitalive determination of CPL and total luminescence intensity as well as the corresponding g ratio are described
