BCNO发光材料发光机理的研究 Title:LuminescenceMechanismsofBCNOLuminescentMaterials Abstract: BCNO(boroncarbonnitrogenoxygen)luminescentmaterialshavegainedsignificantattentionduetotheirversatileapplicationsinoptoelectronics,sensors,andphotocatalysis.ThispaperaimstoreviewtheresearchontheluminescencemechanismsofBCNOmaterials.Itcoversthesynthesismethods,structuralproperties,andvariousluminescencemechanismsincludingdefect-relatedemission,energytransfer,andsurface-statetransitions.TheunderstandingofthesemechanismsiscrucialfortailoringBCNOluminescentmaterialsforspecificapplicationsandadvancingtheirpotentialinthefieldoflightinganddisplaytechnologies. Introduction: BCNOluminescentmaterials,classifiedasanovelclassofcarbonaceouscompounds,haveemergedasapromisingalternativetotraditionalinorganicororganicphosphors.Thesematerialspossessuniquepropertiessuchasexcellentthermalstability,tunablebandgaps,andattractiveluminescenceproperties.However,abetterunderstandingoftheunderlyingluminescencemechanismsisrequiredtounlockthefullpotentialofBCNOmaterialsforvariousapplications.ThispaperprovidesanoverviewofthecurrentstateofresearchontheluminescencemechanismsofBCNOmaterials.
