We have acquired characteristic spectra of a sample consisting of many minerals for the selected frequency luminescence using BG2003 spectronmeter stimulated with red light

green light of a laser source

and a heat source

respectively. And its DE and saturated dose can be obtained under different stimulation conditions. It is clear that different wavelengths can be adopted for dating. The saturated dose measured using BG2003 spectrometer was consistent with that measured using RGD-3D TL equipment

which was equal to 400 Gy.
