Abstract
铅卤钙钛矿纳米晶具有高光致发光量子产率、窄半峰宽和广发光色域的优势, 是众多领域中的理想光电材料. 但釜式制备方法无法实现规模化制备, 限制了钙钛矿纳米晶的市场化应用. 本文设计了一种液滴流微反应器, 为大规模合成高量子产率的钙钛矿纳米晶提供了新方法. 该装置可精确控制纳米晶在130 nL液滴内的生长过程. 与其他合成方法相比, 可以将前驱体浓度提高到文献水平的3–116倍, 将配体与反应物比例降低到热注入法的2%–50%. 通过改变反应温度和停留时间, 探究了纳米晶形貌和光致发光性质之间的构效关系. 此外, 通过在线调整PbX2比例, 可实现单次反应内制备全可见光谱(406–677 nm)发光的纳米晶.
