제목 Fabrication of Perovskite/Poly(ethylene oxide) composite film for red perovskite light-emitting diodes
초록 Organic–inorganic lead halide perovskites are promising candidates for high-performing Light Emitting Diodes due to the high color purity, low cost and simple solution process. In recent years, there have been significant advances in green perovskite LEDs, but not red or blue perovskite LEDs. In this study, we fabricated a red perovskite LEDs with perovskite/polymer composite as the light emitting layer. The emission color of perovskite based on CSPbI3 was adjusted by mixing phenylethylammonium bromide (PEABr) at various molar ratios. The Poly(ethylene oxide)(PEO) was added to perovskite precursor to obtain a perovskite/PEO composite film with improved the stability, surface morphology and photoluminescence, which lead to high efficiency for PeLED.
