摘要：

Lead halide perovskite quantum dots (PQDs) have demonstrated extremely excellent optical properties and great application potential in various optoelectronic devices. However, it is still a challenge to maintain both stability and multipeak emission performance for PQDs. In this work, we successfully synthesize multipeak emission CsPbCl1.5Br1.5:Eu3+-SiO(2 )PQDs employing molecular sieves through high-temperature solid-state reactions, and the energy transfer process is designed to enhance the emission of Eu3+. The excellent thermal stability of as-prepared PQDs has also been proved by thermal cycle test from 25 to 100 C-degrees. Furthermore, the as-prepared doped PQDs are utilized for white light emitting diodes, which show excellent white light performance. The material is expected to be applied as a component on high-quality white LED devices, and our finding is believed to offer a new strategy for designing multipeak emission PQDs.
