Synthesis of quantum dots is a valuable experiment for demonstration and discussion of quantum phenomena in undergraduate chemistry curricula. Recently, a new class of all-inorganic perovskite quantum dots (QDs) with a formula of CsPbX₃ (X = Cl, Br, I) was presented and attracted tremendous attention. Here we adapt the synthesis of CsPbX₃ QDs for implementation in inorganic chemistry laboratory class. Perovskite QDs have a number of advantages: they exhibit bright photoluminescence in the visible range of spectrum with a narrow bandwidth, and their emission wavelength can be changed by tuning both size and composition of nanoparticles. The described experiment provides a discussion point on many important concepts of inorganic chemistry, materials science, and nanotechnology, such as colloidal synthesis of nanoparticles, perovskite crystal structure, quantum size effect, as well as photovoltaics and renewable energy.

铯铯卤化物钙钛矿量子点的合成

量子点的合成是一个有价值的实验，可用于演示和讨论本科化学课程中的量子现象。最近，提出了一种新型的具有CsPbX ₃（X = Cl，Br，I）的全无机钙钛矿量子点（QDs），并引起了极大的关注。在这里，我们改编了CsPbX ₃的合成在无机化学实验室课程中实施的QD。钙钛矿量子点具有许多优点：它们在可见光范围内以窄带宽显示明亮的光致发光，并且可以通过调整纳米粒子的大小和组成来改变其发射波长。所描述的实验提供了关于无机化学，材料科学和纳米技术的许多重要概念的讨论点，例如纳米粒子的胶体合成，钙钛矿晶体结构，量子尺寸效应以及光伏和可再生能源。
