As an important lanthanide (Ln)-based functional materials, the Ln chalcogenides possess unique properties and various applications. However, the controllable synthesis of Ln chalcogenide nanocrystals still faces great challenges because of the rather poor affinity between Ln and chalcogenide ions (S, Se, Te) as well as strong preference of combination with existed oxygen. Herein, a facile but general heterogeneous nucleation synthetic strategy is established toward a series of colloidal ternary Cu Ln sulfides nanocrystals using the Ln dithiocarbamates and CuI as precursors. To extend this synthetic protocol, similar strategy is used to prepare six kinds of high quality CuLnS2 nanocrystals, while the bulk ones are only obtained by the traditional solid-state reaction at rigorous condition. Importantly, high-entropy nanocrystals CuLnS2 and CuEuxLn2-xS3 which contain six Ln elements (Nd, Sm, Gd, Tb, Dy) are readily obtained by the co-decomposed process attributed to their similar diffusion speed. As a proof-of-concept application, CuEu2S3 nanocrystals showed efficient photocatalytic hydrogen production properties.

高效光催化产氢的镧系元素硫化物纳米晶的通用合成策略
作为一种重要的镧系元素（Ln）基功能材料，Ln硫属化物具有独特的性能和广泛的应用。然而，由于Ln与硫族离子（S、Se、Te）之间的亲和力较差以及与存在的氧结合的强烈偏好，Ln硫族化物纳米晶的可控合成仍然面临着巨大的挑战。在此，使用二硫代氨基甲酸盐 Ln 和 CuI 作为前体，针对一系列胶体三元 Cu Ln 硫化物纳米晶体建立了一种简单但通用的异相成核合成策略。为了扩展该合成方案，使用类似的策略制备了六种高质量的CuLnS 2纳米晶体，而块状纳米晶体只能通过传统的固相反应在严格的条件下获得。重要的是，含有六种Ln元素（Nd、Sm、Gd、Tb、Dy）的高熵纳米晶体CuLnS 2和CuEu x Ln 2-x S 3由于它们相似的扩散速度，很容易通过共分解过程获得。作为概念验证应用，CuEu 2 S 3纳米晶体表现出高效的光催化产氢特性。
