Multipeak emission Eu3+-doped perovskite quantum dots in molecular sieve
Source abstract
Abstract
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+–SiO2 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. 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.
