Radiophotoluminescence (RPL)

This chapter covers a wide range of radio-photoluminescence (RPL) technologies, from fundamentals to applications. It presents the definition of the term of RPL and distinguishes it from thermally-stimulated luminescence and optically-stimulated luminescence as a different type of dosimetric technique using a phosphor medium. RPL is a very powerful tool when the measurement environment requires exposure to light or heat. The chapter introduces a list of RPL materials and their fundamental properties, as reported in the literature. The RPL center is typically very stable and the resulting luminescence is due to electronic transitions within the RPL center. The chapter also introduces the principal properties as well as applications of four selected RPL materials with many illustrative materials. These include: Ag-doped sodium-aluminophosphate glasses, Al 2 O 3 :C,Mg, LiF, and Sm-doped compounds. It concludes with a summary of RPL as a luminescent phenomenon used in radiation measurement, and provides future prospects.
