Due　to　the　instability　of　perovskite　quantum-dots　(PQDs),　their　applications　in　optoelectronic　devices,　in　reality,　are　limited.　In　this　paper,　Cs(Pb,Sb)Br-3　PQDs@glasses　were　successfully　prepared　by　traditional　melting　quenching　and　heat　treatment　methods.　The　optical　characterization　shows　that　Cs(Pb0.7Sb0.3)Br-3　PQDs@glasses　has　an　emission　peak　of　518　nm　and　a　full　width　at　half　maximum　of　20　nm,　and　the　photoluminescence　quantum　yield　(PLQY)　is　58%.　The　electronic　structure　of　Cs(Pb0.875Sb0.125)Br-3　has　been　studied　by　first　principles.　The　stable　range　of　chemical　potential　of　each　element　in　CsPbBr3　is　calculated　by　first　principles.　It　is　proved　that　CsPbBr3　is　an　excellent　PQDs　luminescent　material.　The　thermal　analysis　and　temperature-dependent　photoluminescence　spectra　prove　the　stability　of　the　PQDs@glass　within　200　degrees.　The　thermal　distribution　of　the　sample　under　laser　irradiation　is　measured　by　a　finite　element　method.　In　addition,　Cs(Pb,Sb)Br-3　PQDs@glasses　are　combined　with　AlN-(Ca,Eu)AlSiN3　ceramic　phosphors　to　prepare　phosphor　wheels,　which　shows　that　these　materials　have　potential　application　prospects　in　the　field　of　display.
