Developing　luminescent　materials　with　suitable　correlated　color　temperature　(CCT)　and　sufficient　color-rendering　index　(CRI)　is　a　challenging　problem　in　the　field　of　commercialized　warm　white　LED　lighting.　Herein,　a　novel　metal-organic　gel　(MOG)　material　named　YTU-G-1(SE)　was　synthesized,　consisting　of　zirconium　metal　coordinated　with　1,1,2,2-tetrakis(4-carboxyphenyl)　ethylene.　YTU-G-1(SE)　exhibits　strong　fluorescent　properties　with　an　aggregation-induced　emission　(AIE)　effect,　emitting　yellow-green　fluorescence　at　515　nm.　The　internal　and　external　quantum　efficiencies　(IQE/EQE)　of　YTU-G-1(SE)　are　close　to　unity,　with　values　of　95.74　±　0.5%　and　88.67　±　0.5%,　respectively.　Finally,　we　combined　YTU-G-1(SE)　with　a　commercial　blue　chip　and　a　commercial　red　phosphor　(Sr,Ca)AlSiN3:Eu2+　to　fabricate　a　warm　white　light　LED　with　a　color　temperature　of　3736　K,　a　color-rendering　index　Ra　of　88.2,　and　a　lumen　efficiency　of　79.42　lm　W−1.　This　work　provides　a　new　approach　to　regulating　the　emission　of　AIE　and　offers　a　novel　idea　for　developing　high-performance　warm-white　pc-WLEDs.　©　2024　The　Royal　Society　of　Chemistry
