摘要

开发了一种基于卤素灯光源的光激发光(OSL)单元,用于石英样品的激发。除了卤素光源外,OSL单元还包含一个红外二极管阵列,用于长石样品的红外受激发光(IRSL)测量和石英纯度筛选。新的OSL装置可以直接安装在自动化的RisøTL测年仪上。从卤素灯过滤的刺激光谱在样品处提供约16mW cm-2。描述了石英样品的初步OSL研究,并给出了测年结果。

A new system for measuring optically stimulated luminescence from quartz samples

An optically stimulated luminescence (OSL) unit based on a halogen lamp light source has been developed for the stimulation of quartz samples. In addition to the halogen light source, the OSL unit incorporates an infra-red diode array for infra-red-stimulated luminescence (IRSL) measurements of feldspar samples and for screening the purity of quartz. The new OSL unit can be fitted directly onto the automated Risø TL dating apparatus. The stimulation spectrum filtered from the halogen lamp delivers about 16mW cm-2 at the sample. Preliminary OSL studies of quartz samples are described, and dating results are presented.
