摘要
本文针对一种钾长石矿物作了其选频释光图谱的研究分析.在BG2003光释光谱仪上选择不同的激发光源对钾长石样品进行激发,获得了钾长石的释光图谱.通过对这种钾长石的研究,发现矿物随辐射剂量增加响应有很好的线性关系,可以用来做释光测年的矿物.这种钾长石的测年上限大约是84万年.它的光晒退实验指出利用这种钾长石矿物测年时要考虑光晒退的影响.
As a sample, feldspar（ KCFW01 ） has been tested with BG2003. We selected different wavelength of the stimulating source and got the emission photons of the feldspar. Therefore, some luminescence properties of this feldspar have been obtained. It is very important for the sample. There are two characteristic wavelengths have a nice luminescence response for the radiation doses. And a range of 840 thousand years can be using for dating. Some techniques for luminescence dating have been discussed in present paper.
