Cesium lead halide (CsPbX3) perovskite nanocrystals (NCs) have demonstrated extremely excellent optical properties and great application potentials in various optoelectronic devices. However, because of the anion exchange, it is difficult to achieve white-light and multicolor emission for practical applications. Herein, we present the successful doping of various lanthanide ions (Ce3+, Sm3+, Eu3+, Tb3+, Dy3+, Er3+, and Yb3+) into the lattices of CsPbCl3 perovskite NCs through a modified hot-injection method. For the lanthanide ions doped perovskite NCs, high photoluminescence quantum yield (QY) and stable and widely tunable multicolor emissions spanning from visible to near-infrared (NIR) regions are successfully obtained. This work indicates that the doped perovskite NCs will inherit most of the unique optical properties of lanthanide ions and deliver them to the perovskite NC host, thus endowing the family of perovskite materials with excellent optical, electric, or magnetic properties.

将镧系元素掺入钙钛矿纳米晶体中：高度改善和扩展的光学性能
卤化铯铅（CsPbX 3）钙钛矿纳米晶体（NCs）已显示出极佳的光学性能和在各种光电设备中的巨大应用潜力。然而，由于阴离子交换，在实际应用中难以实现白光和多色发射。在这里，我们介绍了成功地将各种镧系离子（Ce 3+，Sm 3+，Eu 3+，Tb 3+，Dy 3+，Er 3+和Yb 3+）掺杂到CsPbCl 3的晶格中钙钛矿NCs通过改进的热注射方法。对于掺杂镧系离子的钙钛矿型NC，成功地获得了高光致发光量子产率（QY）以及从可见光到近红外（NIR）区域的稳定且可广泛调谐的多色发射。这项工作表明，掺杂的钙钛矿NC将继承镧系元素离子的大多数独特光学性质，并将其传递给钙钛矿NC主体，从而赋予钙钛矿材料族以优异的光学，电或磁性能。
