Abstract

Optical absorption (OA) dose response is modeled in the framework of a single electron-trapping-center (TC), single hole-luminescent-center (LC) and single electron-competitive-center (CC). It is demonstrated that the "always-experimentally-observed" linear/exponentially saturating OA dose response arises if there is approximate equality (within an order of magnitude) of the dose filling constants and the total available trap density associated with the TC and CC, as is apparently the case in LiF:Mg,Ti (TLD-100) and other investigated TL materials. In principle, however, OA dose response supralinearity can occur if either of these are sufficiently dissimilar leading to early saturation of one of the electron trapping entities.
