A facile colloidal synthesis of highly ionic cesium halide nanocrystals is reported. Colloidal nanocrystals of CsI, CsCl and CsBr with unprecedentedly small dimensions are obtained using oleylammonium halides and cesium oleate as precursors. The ease and adaptability of our method enables its universalization for the formation of other highly ionic nanocrystals.

报道了一种简便的用于合成高离子性卤化铯纳米晶体的胶体合成方法。使用卤化油胺和油酸铯作为前驱体，获得了尺寸前所未有的小的CsI、CsCl和CsBr胶体纳米晶体。我们方法的简便性和适应性使其能够普遍用于形成其他高离子性纳米晶体。
