| 摘 要： | 通过最新研制的三维热释光光谱测量仪器，对长石热释光光谱的分析，,可以寻找其各个波段热释光信号的响应灵敏度差异。测试结果表明，长石矿物不同波长段的热释光量随辐照剂量的增加，呈现不同的增长特性；同时，长石热释光谱图显示出热释光信号光谱的红光／红外光波段的能量释放比相应蓝／紫光波段的能量的释放，提前大约10℃产生，但是各自能量释放的峰值几乎发生在同一温度处。样品发出的热释光中红光部分的峰峰值与紫光部分的峰峰值相比较，有明显的差别，三维谱图显示出该样品分布在从绿光波段直到红光／远红外光波段（500－850nm）的热释光量，明显比分布在紫光波段附近的相应热释光量要大的多。

| Abstract: | The thermoluminescent characteristic of feldspar has been studied ever since. A new study method for thermoluminescence spectra of feldspar, based on characteristics of thermoluminescence spectra of some typical feldspar samples, is presented in this paper. It is also pointed out that it will play an important role in feldspar dating research while selecting one reasonable thermoluminescence peak at appropriate wavelength, due to the different features of thermoluminescence peaks at different wavelength, especially of thermoluminescence sensitivity to radiation doses, |
