A　series　of　Ce3+-doped　Gd2O3-GdF3-Al2O3-B2O3-SiO2　glass　scintillators　(GSCx　and　GLCx)　were　successfully　synthesized　in　reducing　atmosphere　for　future　imaging　application.　The　transmittance　of　GSCx　glasses　exceeds　85　%　in　range　of　500–800　nm,　and　the　cut-off　edge　red　shifts　as　the　Ce3+　concentration　increases.　In　photoluminescence　(PL),　GSCx　glass　scintillators　have　a　360–600　nm　broadband　emission　with　a　shoulder　peak　at　around　450　nm.　Meanwhile,　the　PL　lifetime　of　GSCx　glasses　is　close　to　the　CeF3　crystals,　and　the　PL　QY　of　GSC3　glass　scintillator　reaches　up　70.2　%.　For　scintillation　application,　the　integral　XEL　intensity　of　GSC2　and　GSC3　glasses　is　31.3　%　and　24.4　%　of　that　of　BGO　crystal.　GLC2　and　GLC3　glasses　exhibit　similar　spatial　resolution　of　approximately　7　lp·mm−1.　Moreover,　the　light　yields　of　GSC2　and　GSC3　glass　scintillator　are　1702　and　1690　ph/MeV　excited　by　γ-ray,　respectively.　The　nonproportionality　of　GSCx　glasses　is　less　than　3　%　in　the　range　of　100–1400　keV　due　to　the　large　density　and　Zeff.　As　Ce3+　concentration　increases,　both　the　fast　and　slow　components　of　the　glasses　decrease　(103.7　ns–89.7　ns,　1454.4　ns–1012.8　ns),　and　the　proportion　of　fast　component　also　increased　from　3.3　%　to　4.7　%.　For　γ-ray　imaging,　the　scintillation　light　events　of　the　glass　can　be　observed　from　SiPM　array,　and　the　central　position　(−2,　−1)　have　the　highest　count　rate　of　the　system.　The　results　show　that　GSCx　and　GLCx　glass　scintillators　deserve　further　development　for　future　applications.　©　2025
