Figure 1. (A) Schematic illustration of the three-source co-evaporation process used to prepare cerium-based halide-organic composites; (B) PL spectra of cerium-based halide-organic composites films under 350 nm excitation; (C) TRPL decay curves of cerium-based halide-organic composites under 350 nm excitation with monitoring at 405 nm; (D) TRPL decay curves of the same films monitored at 560 nm. PL: Photoluminescence; TRPL: time-resolved photoluminescence; CBP: 4,4′-Bis(N-carbazolyl)-1,1′-biphenyl; mCBP: 3,3′-Bis(carbazol-9-yl)biphenyl; TCTA: 4,4′,4′′-Tris(carbazol-9-yl)triphenylamine; EM: emission.
