The infrared emission in radioluminescence of feldspar crystals determines the received irradiation dose. This recently discovered phenomenon can be used for dating the last light exposure of feldspar grains (e.g. sediments). From the physical point of view, there is particular relevance to the infrared optically stimulated luminescence, because both deal with the same light sensitive electron trap. Data from light stimulation experiments (ultraviolet to infrared) suggest that a localized transition is most likely to be responsible for the infrared optically stimulated luminescence and that this process is possible for only a relatively small proportion of trapped electrons. The infrared radioluminescence signal gives direct information about the trapped charge density of the electron trap. A new model, described in terms of a band scheme, has been successfully used to interpret the observed data.
