What Does OSL Stand For?
OSL stands for Optically Stimulated Luminescence
Optically Stimulated Luminescence (OSL) is a geological and archaeological dating technique that measures the amount of trapped electrons in mineral grains, such as quartz and feldspar, which have been exposed to ionizing radiation over time. By stimulating the sample with light, OSL releases stored energy as luminescence, providing a means to determine the last time the minerals were exposed to sunlight or heat. This method is widely used for dating sediments and artifacts, offering insight into ancient environments and human activities.
