| 제목 | Design of high stable perovskite film to generate warm white light for application in light emitting diodes |
| 초록 | Cesium lead halide perovskite light emitting materials have attracted attention by these high color purity and stability. The narrow full width at half maximum (FWHM) and low cost of raw materials makes halide perovskite materials highly potential advanced materials for applications in light emitting diodes. Furthermore, low energy synthesis process and possibility of output product to be either solution or powder, adds to widespread applications. Extra-ordinary optical properties make halide perovskite favored materials for next generation lighting materials. In this study, CsPb(Br0.4, I0.6)3 was synthesized by hot injection method and blended with ethyl cellulose and poly-methylmetacrylate based films to generate warm white using with conventional inorganic YAG:Ce3+. Fabricated cesium lead halide perovskite films showed outstanding characteristics FWHM of 32nm and high luminous efficacy of 46.45 lm/W. We propose the CsPb(Br0.4, I0.6)3 perovskite QDs with ethyl cellulose as a promising red-emitting material and a color converter which can replace the conventional inorganic phosphor. |
