SIRIOL: A Sensitive InfraRed Instrument for phOto Luminescence measurements of feldspar

The new InfraRed PhotoLuminescence (IRPL) signal in feldspar offers a promising alternative to the wellestablished OSL method to recover the absorbed radiation dose for dating purposes. The non-destructive readout using Stokes shifted photoluminescence offers the opportunity to carry out repeat measurements to improve the signal to noise ratio, and the steady state signal enables straightforward spatially and spectrally resolved measurements.
