Enhancing the phosphorescence of hybrid metal halides through molecular sensitization

Herein, a zero-dimensional (0D) hybrid organic-inorganic metal halide (OIMH) [BPy] 6 [Pb 3 Br 12 ] (BPB, BPy = N -butylpyridinium) as a room-temperature phosphorescent (RTP) material is synthesized. Through molecular sensitization, its RTP quantum efficiency can be increased by a maximum of 14-fold....

Zusammenfassung:Herein, a zero-dimensional (0D) hybrid organic-inorganic metal halide (OIMH) [BPy] 6 [Pb 3 Br 12 ] (BPB, BPy = N -butylpyridinium) as a room-temperature phosphorescent (RTP) material is synthesized. Through molecular sensitization, its RTP quantum efficiency can be increased by a maximum of 14-fold. A white-light-emitting device is obtained via a solvent-free and eco-friendly melting method. The room-temperature phosphorescence quantum efficiency of [BPy] 6 [Pb 3 Br 12 ] has been improved by a maximum of fourteen-fold through sensitization of thiadiazole-based molecules.
