On-and-off feedback control with hysteresis algorithm for automatic flow chemistry synthesis of the desired MAPbBr X I 3-X quantum dot |
| 초록 |
The advancements in the synthesis of hybrid organic-inorganic halide perovskite quantum dots (HP-QDs) have demonstrated their flexibility and prospective uses in photovoltaics and light sources. However, the compositional complexity of mixed-cation and/or mixed-halide HP-QDs would need repeated optimization steps to get the appropriate perovskite crystals via batch-scale chemistry, resulting in increased time, labor, and expense. To handle this issue, we provide a dynamic flow synthetic system that uses an on-and-off feedback control with a hysteresis algorithm to automatically synthesize methylammonium lead trihalide perovskite quantum dots (MAPbBr X I 3-X QDs with 0 ≤ X ≤ 3) with a targeted emission wavelength. As a result, the required MAPbBr X I3-X QDs could be generated in an automated way through feedback control, implying an advanced flow chemistry synthetic platform capable of producing on-demand nanomaterials with high efficiency. |
