Abstract
Fully inorganic lead halide perovskite materials have attracted tremendous attention because of their practical applications in optoelectronic devices, such as light emitting diodes. In this work, we report the first development of highly efficient, stable and green-emitting CsPbBr3 perovskite NCs with a PE microcapsule. The CsPbBr3 perovskite NCs were perfectly incorporated inside the PE microcapsule with a multi-lamellar structure, which shows better luminescence characteristics such as a high PLQY and thermal stability Furthermore, our results revealed the high luminous performance with a white conversion efficacy of 62.4 lm W−1, EQE of 31.8%, CRI of 37.01, and CCT of 6028 K on blue emitting InGaN LED chip. We suggest that our material will be one of the next generation candidate luminescence materials for application in optoelectronic devices.
