LED industry in china develops rapidly. Yttrium aluminitum garnet （YAG） phosphors are widely applied in white LEDs. The Instrument Systems company＇s Spectro320e spectrometer is suitable for accurate measurement of the spectrum. It is combined in this paper with the Everfine company＇s PE-5 phosphor excitation device to achieve the accurate testing of yellow YAG phosphors excited by blue light, such as chromaticity coordinates, relative brightness and quantum efficiency. We also studied the influence of different testing conditions on the results, such as dark current, PMT and density filter. The cautions are provided here when using the Spectro320e spectrometer.
