摘要
近年来，钙钛矿纳米晶由于具有优异的光电性质，在发光、光电转换等领域获得了广泛的研究，已然成为科研界的“明星材料”。然而，钙钛矿纳米晶存在一些不足之处(例如稳定性差、光谱仅限于可见光区等)，限制了其应用。稀土离子具有丰富的4f能级和特殊的电子构型，因此，将稀土离子掺杂到钙钛矿纳米晶中，能够显著提升材料的光电性质，并改善稳定性，解决钙钛矿纳米晶面向实际应用需求的关键问题。本文详细介绍了稀土掺杂钙钛矿纳米晶的性质，重点对材料在发光二极管、太阳能电池以及光电探测器等多个方面的应用实例进行了总结与展望。
Abstract
In recent years
due to their excellent photoelectric properties
perovskite nanocrystals have been extensively studied in the fields of luminescence and photoelectric conversion
and they have become "star materials" in scientific research circles. However
perovskite nanocrystals have some shortcomings(such as poor stability
the spectrum is limited to the visible light region
etc
.)
which limit their application. Rare earth ions have abundant 4f energy levels and special electronic configurations. Therefore
doping rare earth ions into perovskite nanocrystals can significantly improve the photoelectric properties of the material
improve the stability
and solve the key problem of the perovskite nanocrystals for practical application requirements. We introduce the properties of rare earth-doped perovskite nanocrystals
and focus on the application of materials in light-emitting diodes
solar cells
and photodetectors
respectively.
