Abstract：

Scintillators　self-calibrated　for　both　temperature　and　radiation　dose　are　highly　needed　for　X-ray　imaging　applications　in　fluctuating　conditions.　In　this　work,　a　dual-peak　emitting　scintillator　glass　codoped　with　CsPbBr3　nanoparticles　(NPs)　and　rare　earth　ions　Eu3+　are　prepared.　The　fluorescence　intensity　ratio　(FIR)　of　the　non-thermally　coupled　green　and　red　emissions　of　CsPbBr3　and　Eu3+　is　employed　as　the　self-calibration　indicator　for　temperature　and　X-rays　dose.　A　comparison　is　given　to　CsPbBr3　or　Eu3+　singly-doped　and　CsPbBr3/Eu3+　codoped　glasses,　with　respect　to　their　photoluminescence　and　X-ray　excited　luminescence.　The　existence　of　energy　transfer　between　CsPbBr3　and　Eu3+　is　discussed.　The　different　responses　to　temperature　and　X-ray　dose　rate　of　CsPbBr3　NPs　and　Eu3+　are　clearly　revealed.　The　study　highlights　the　potential　of　non-contact　techniques　for　safe　and　accurate　temperature　and　radiation　dose　measurements.　©　2025　Elsevier　Ltd　and　Techna　Group　S.r.l.
