| 제목 | High-efficient white light-emitting diodes based on green-emitting CsPbBr3 halide perovskite films with enhanced stability |
| 초록 | Recently, all-inorganic cesium lead halide CsPbX3 (X=Cl, Br, I) perovskite nanocrystals(NCs) have drawn a lot of attention because of their remarkable optoelectronic properties such as high quantum yields (PLQYs), narrow full width at half maximum (FWHM) and tunability of their optical band gap over the entire visible light spectral range. Because of these outstanding properties, halide perovskite NCs are promising materials for light emitting devices. In this work, high quality green-emitting colloidal CsPbBr3 perovskite NCs were synthesized by the simple hot-injection method. In order to apply CsPbBr3 NCs for white LEDs, CsPbBr3 green film was fabricated with ethyl cellulose (EC). Synthesized perovskite NCs film are characterized to define crystal structures, luminescence properties, and morphologies. We optimized luminescence properties of CsPbX3 NCs for a white generation in the application of LEDs. We fabricated CsPbBr3 green film with ethyl cellulose having good mechanical properties. |
