摘要：

Various kinds of scattering light should be eliminated in fluorescence and phosphorescence analysis. Constant-wavelength and constant-energy synchronous scanning have the advantages of reducing first-order scattering lights. When excitation wavelength is far from emission wavelength, one should pay attention to second-order scattering light. We found second-order scattering light can be suppressed by using variable-angle synchronous luminescence spectroscopy (VASLS). In this paper, the principle and method of eliminating second-order scattering light will be presented.
