Research article demonstrates enhanced phosphorescence in hydroxyapatite with organic chromophores, suggesting improved materials for lighting.
In Research Article e8043102, Tao Wang, Guoqing Zhang, and co-workers embeds carboxylated organic chromophores into the hydroxyapatite (HAP) lattice. The rigid inorganic matrix efficiently restricts molecular motions, while the local electric field and internal energy traps boost triplet exciton generation. This strategy yields highly efficient room-temperature phosphorescence, which persists even at a high temperature of 500 K.
