Surface sand samples were collected in eight sites of the Horqin and Otindag deserts located in north to Beijing. BG2003 luminescence spectrograph was used to analyze the emitted photons and characteristic spectra of the selected frequency luminescence were obtained. It was found that high intensities of emitted photons stimulated by heat from 85°C–135°C and 350°C–400°C. It belong to the traps of 4.13 eV(300 nm)

4.00 eV(310 nm)

3.88 eV(320 nm) and 2.70 eV(460 nm)

and the emitted photons belong to traps of 4.00 eV(310 nm)

3.88 eV(320 nm) and 2.70 eV(460 nm) were stimulated by green laser. And sand samples of the eight sites can respond to the increase of definite radiological dose at each wavelength

which is the characteristic spectrum to provide radiation dosimetry basis for dating. There are definite district characteristic in their characteristic spectra.
