Infrared photoluminescence IRPL

This paper describes a system for measurement of the IRPL signal from single sand-sized grains of feldspar. The attachment uses an electron-multiplying charge-coupled device (EMCCD) imaging system, and has two innovations that make it possible to use such a detector to obtain IRPL data.

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.

Techniques for spatially resolved measurements of infrared-stimulated luminescence (IRSL) and novel Infraredphotoluminescence (IRPL) emissions have recently been developed for applications of rock surface dating.
