Luminescence thermal quenching of phosphors is one of the prominent problems in restricting their application in high-power LED devices. In the current work, tunable luminescence thermal quenching behaviors, including abnormal negative thermal quenching and normal thermal quenching, were demonstrated for Na3Sc2(PO4)3Eu2+ phosphors tailored by phase transformation details. A series of ionic substitution schemes were employed to synthesize α-, β- and γ-Na3Sc2(PO4)3Eu2+ phosphors, which show discrepant phase transformations during heatin
