Abstract
Radiophotoluminescence (RPL) is a phenomenon where new luminescence centers are formed in a material due to its interaction with ionizing radiation. The number of generated luminescence centres, or RPL centres, is proportional to the deposited radiation energy or dose, which, in turn, correlates with the luminescence intensity. Consequently, the luminescence signal can be employed to estimate the radiation dose. In recent years, the application of RPL in fluorescence nuclear track detectors (FNTD) has garnered significant attention. However, studies have predominantly focused on conventional RPL materials, which are limited to Al2O3:C,Mg, LiF, and Ag-doped Na2O-Al2O3-P2O5 (NAP) glass. It is imperative to advance both material development and system integration to optimize these technologies, as the lack of comprehensive knowledge on material design remains a primary challenge. In this work, we conducted a systematic comparison of basic RPL properties and FNTD performance among Ag-doped Li2O-Al2O3-P2O5 (LAP), Na2O- Al2O3-P2O5, and K2O- Al2O3-P2O5 (KAP) glasses to elucidate the effects of alkali metals.
