Description
Summary:Ionising radiation are detected via optically stimulated luminescence (OSL). In optically stimulated luminescence (OSL), a preirradiated sample is excited by light in the visible/infrared region, which results in the detachment of either the hole or the electron. Recombination then causes the emission of radiation with a shorter wavelength than the exciting radiation. The best options for OSL phosphors are those materials that emit light with a wavelength between 350 and 425 nm and have strong photo-ionization cross sections in the blue-green (450–550 nm) or infrared (650–800 nm) regions. Since most fluorides satisfy these requirements when doped with ions like Cu, Ag, or Eu, they have been researched for use in OSL dosimeter development. Various fluorides include Fluoride pervoskites, ABF3 (A;, Na,K: B-Mg,Ca) fluorides with Colquiriite structure (LiCaAlF6), alkali silico fluorides, alkali fluorides, alkaline earth fluorides, and fluoride pervoskites were explored. The OSL in various fluorides is reviewed in this work along with how it can be used in OSL dosimetry.
