The　development　of　efficient　dual-emissive　and　temperature-sensitive　luminescent　materials　is　critical　for　advancing　non-contact　optical　thermometry.　Herein,　we　employed　a　co-doping　strategy　to　enhance　energy　transfer　pathways　in　Ca9Ga(PO4)7　phosphors.　Under　331　nm　excitation,　dual　emissions　from　Eu2+　(415　nm)　and　Cr3+　(696　nm)　were　achieved,　with　Zn2+　enhancing　the　near-infrared　(NIR)　of　Cr3+.　The　optimal　Cr3+　concentration　led　to　an　approximately　six-fold　increase　in　NIR　emission　intensity,　attributed　to　Eu2+-induced　crystal　field　modulation　and　efficient　dipole-dipole　energy　transfer,　which　are　evidenced　by　comparing　the　emission　spectra　and　decay　curve　lifetimes.　Temperature-dependent　emission　spectra　revealed　that　Eu2+　emission　remained　stable,　while　Cr3+　emission　exhibited　significant　temperature　sensitivity　in　Ca9Ga(PO4)7:Zn2+,Eu2+,Cr3+,　enabling　precise　temperature　sensing　with　a　peak　sensitivity　of　1.256　%　K−1　at　298　K.　This　work　offers　a　novel　approach　to　improving　energy　transfer　efficiency　and　dual-emission　properties,　contributing　to　the　development　of　high-performance,　real-time　optical　thermometry　and　photonic　technologies.　©　2025　Elsevier　B.V.
