A novel X-ray excited luminescence spectrometer is designed and set up based on the time correla-ted single photon counting technology. This spectrometer realized is effectively utilized to detect the X-ray ex-cited luminescence and afterglow spectra of scintillating materials,even in the case of weak scintillators. The testing for the famous CsI( Tl) ,LYSO( Ce) scintillating crystals and Tb3+-activeted silicate scintillating glasses is considerably verified to be reasonable. All the testing results suggest that the developed X-ray excited lumi-nescence spectrometer can be well fit the researching and developing requirements of scintillating materials.
