Face-open nanoboxes of lead telluride and selenide have been synthesized by a simple hydrothermal method. Nano- and microcrystals of various morphologies, including microflowers, semi-microflowers, cubic nanoparticles, etc., have also been observed at different synthesis conditions. Temperature, time, and concentrations of various reactants play a major role in controlling the morphology and shape evolution of the product. This simple synthesis technique for the growth of various nano- and microstructures opens a new route to prepare hierarchical structures of a variety of binary semiconducting materials in a large quantity. A possible growth mechanism of such nano- and microstructures has been proposed.
通过一种简单的水热法合成了碲化铅和硒化铅的面开放纳米盒。在不同的合成条件下，还观察到了各种形态的纳米晶体和微晶，包括微花、半微花、立方纳米颗粒等。温度、时间以及各种反应物的浓度在控制产物的形态和形状演变方面起着主要作用。这种用于生长各种纳米和微结构的简单合成技术为大量制备各种二元半导体材料的分级结构开辟了一条新途径。已经提出了这种纳米和微结构的一种可能生长机制。
