铅卤化物 perovskite 量点(PQD ) 的稳定性被在 carboxybenzene microcrystals 嵌入他们改进。结果塑造针的混合 microcrystals 保存了 PQD 的强壮的光致发光。与以前报导的包含聚苯乙烯的 PQD 相比, carboxybenzene 晶体是柔韧的并且保护了点免受潮湿和 photodegradation 的伤害。提高的稳定性被归因于 carboxybenzene microcrystals 的紧密的矩阵,它保护了 PQD 免受潮湿的伤害。这万用的策略保护了各种各样的 QD,包括所有无机的 PQD 和 chalcogenide QD (例如, CdSe/ZnS QD 和 CuInS/ZnS QD ) 。它提供保护 PQD 的一个灵巧、万用的方法并且可以启用应用在固态有象显示,激光,和轻射出二极管那样的高颜色质量要求的系统。
The stability of lead halide perovskite quantum dots (PQDs) was improved by embedding them in carboxybenzene microcrystals. The resulting needle-shaped mixed microcrystals preserved the strong photoluminescence of the PQDs. Compared with previously reported polystyrene-encapsulated PQDs, the carboxybenzene crystals were robust and protected the dots from moisture and photodegradation. The enhanced stability was attributed to the tight matrix of carboxybenzene microcrystals, which protected the PQDs from moisture. This versatile strategy protected various QDs, including all-inorganic PQDs and chalcogenide QDs (e.g., CdSe/ZnS QDs and CuInS/ZnS QDs). It provides a facile and versatile method of protecting PQDs and may enable applications in solid-state systems with high color quality requirements such as displays, lasers, and light emitting diodes.
