Abstract：

Scintillator　glasses　have　the　potential　for　X-ray　imaging　owing　to　their　low　production　cost,　controllable　shape　and　size,　and　uniform　ion-doping　concentration.　In　this　study,　Tb3+-doped　and　Ce3+/Tb3+-co-doped　oxyfluoride　scintillator　(C4T9)　glass　samples　were　fabricated　by　high-temperature　melting　and　quenching.　In　addition,　the　luminescence　properties　of　the　glass　samples　and　the　discrepancy　in　the　energy　transfer　mechanism　between　Ce3+　and　Tb3+　under　ultraviolet　(UV)　light　and　X-ray　excitation　were　investigated.　The　C4T9　glass　sample　showed　excellent　integral　scintillation　efficiency　of　84.1%　for　commercial　Bi4Ge3O12　(BGO)　crystals.　The　spatial　resolution　of　the　C4T9　glass　sample　was　higher　than　that　of　the　commercial　BGO　crystal　with　42.29　mGy　s−1　X-ray　irradiation,　reaching　16　lp·mm−1.　C4T9　glass　is　expected　to　become　a　key　material　in　medical　imaging,　safety　inspection,　industrial　inspection,　and　other　fields.　©　2023　Elsevier　Ltd　and　Techna　Group　S.r.l.
