TL (thermoluminescence) and OSL (optical stimulated luminescence) of mineral samples are often used to geological dating. The 3D thermoluminescence spectra of several kinds of mineral

such as quarts

potassium feldspar

sodium feldspar and mullite were measured. For the samples of quartz

the wavelengths are ranged from 350 nm to 600 nm

and mainly low temperature glow peaks are observed. The results show that luminescence intensity of quartz from Jiangxi is weaker than that from Gansu

it means that the luminescence characteristics depend on the sample region. The TL peaks of feldspar are rather complex

the wavelength is ranged from 300 nm to 750 nm

and the high temperature peaks are observed. The wavelengths of quartz and feldspar are rather broad and cover the detectable scope of the optical filter

hence quartz and feldspar can contribute more thermoluminescence in geological dating than that of mullite.
