摘要

卤化物钙钛矿纳米晶体是一种很有前途的光电材料。金属掺杂提供了进一步提高其性能的途径,例如,通过增强光发射,或提供额外的功能,如纳米级磁性和极化控制。然而,使用传统的热注射合成方法无法合成具有可控掺杂水平的宽尺寸可调纳米晶体,这阻碍了对掺杂对器件应用的影响的系统研究。在这里,我们报告了一种在环境条件下精确控制金属掺杂钙钛矿纳米晶体尺寸和掺杂浓度的通用合成方法。我们的室温方法导致CsPbX3纳米晶体(X = Cl, Br, I)与各种过渡金属M2+ (M = Mn, Ni, Zn)的完全尺寸可调的等价掺杂。这使我们第一次能够在迄今为止报道的弱约束范围之外获得小而精确的掺杂量子点。它也使得跨多种尺寸和掺杂体制的光物理比较研究成为可能,其中我们显示掺杂诱导的局部化在量子限制效应中占主导地位。因此,这种可推广、简便的合成方法为在工业相关条件下用于发光技术的钙钛矿纳米晶体工程提供了工具箱。

Metal Doping of Strongly Confined Halide Perovskite Nanocrystals under Ambient Conditions

Halide perovskite nanocrystals are promising materials for optoelectronic applications. Metal doping provides an avenue to boost their performance further, e.g., by enhancing light emission, or to provide additional functionalities, such as nanoscale magnetism and polarization control. However, the synthesis of widely size-tunable nanocrystals with controlled doping levels has been inaccessible using traditional hot injection synthesis, preventing systematic studies on dopant effects toward device applications. Here, we report a versatile synthesis method for metal-doped perovskite nanocrystals with precise control over size and doping concentration under ambient conditions. Our room temperature approach results in fully size-tunable isovalent doping of CsPbX3 nanocrystals (X = Cl, Br, I) with various transition metals M2+ tested (M = Mn, Ni, Zn). This gives for the first time access to small, yet precisely doped quantum dots beyond the weak confinement regime reported so far. It also enables a comparative study of the photophysics across multiple size and dopant regimes, where we show dopant-induced localization to dominate over quantum confinement effects. This generalizable, facile synthesis method thus provides a toolbox for engineering perovskite nanocrystals toward light-emitting technologies under industrially relevant conditions.
