Abstract
We report an electric pressure cooker for large-scale synthesis of water-soluble Cu-In-S/ZnS core/shell quantum dots. Low-cost thioglycolic acid and sodium citrate were used as the dual stabilizers. ∼3 grams of quantum dots with a tunable emission from 545 to 610 nm and quantum yield up to 40% were obtained in a batch.
摘要
我们报告了一种用于大规模合成水溶性 Cu-In-S/ZnS 核/壳量子点的电压力锅。使用低成本的硫代乙醇酸和柠檬酸钠作为双重稳定剂。一锅法可得到多达 3 克的量子点，其发射波长可调范围为 545 至 610nm，量子产率高达 40%。
