Photoluminescence, scintillation, and dosimetric properties of Ce-codoped MgF2:Tb ceramics

Analysis of Photoluminescence and Dosimetric Properties of (Ce, Tb)-codoped Magnesium Orthosilicate Single Crystals

“…(19,20) However, Mg 2 SiO 4 codoped with Ce 3+ and Tb 3+ ions has not been researched, although the utility of this combination has been verified for other host materials. (21)(22)(23) Since Ce can take a tetravalent state in addition to a trivalent state, Ce 3+ and Ce 4+ ions are expected to act as hole and electron trap centers, respectively, which would improve the TSL intensity.…”

Growth, Optical, and Scintillation Properties of (Gd0.4Lu0.6)8Sr2(SiO4)6O2 Crystals

“…(21)(22)(23)(24)(25)(26) In the latter, the functionalities of absorption and emission are assigned to the host and emission center, respectively. (27) The recent trend of R&D is on the former type, and preferable emission centers are Ce 3+ , (28)(29)(30)(31)(32)(33)(34) Pr 3+ , (35)(36)(37)(38) some rare-earth ions, (39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51) and other ions that have electron transitions associated with luminescence. (52)(53)(54)(55)(56)(57) The attraction to the emissioncenter-doped scintillators is explained by the controllability of emission wavelength and decay time, and among such emission center ions, Ce 3+ is the most attractive owing to a good match of the emission wavelength with common PMTs, a fast decay time of typically several tens to hundreds of nanoseconds, and a relatively high probability to achieve a high scintillation light yield (LY).…”
