摘要：

钙钛矿纳米材料的研究取得了飞速发展:一方面,合成方法不断涌现,已经可以实现从零维纳米晶、一维纳米线到二维纳米片的形貌精确控制,对其尺寸和维度依赖的光学性质认识也不断深入;另一方面,钙钛矿纳米材料的光学和光电子应用也得到了快速发展,其中,基于钙钛矿量子点的光致发光和电致发光技术最受关注。由于钙钛矿的天然层状结构,通过配体调控很容易制备出二维纳米材料,其发光性能可以通过层数和组分进行调节,最高量子产率超过85%,且具有偏振发光特性,有望成为一类新型发光材料。本文从制备方法、光致发光和电致发光应用等方面综述了基于钙钛矿二维纳米材料的进展,并对其未来的发展方向进行讨论。

Abstract:

Halide perovskites have received great attentions due to their interesting optical properties and potential optoelectronic applications. Due to the intrinsic layered structure, halide perovskite based two-dimensional nanomaterials can be controlled by adjusting the thickness in the nanoscale dimension. In this review, we present the progress of halide perovskite based two-dimensional nanomaterials with a focus on synthesis, optical properties and electroluminescence devices. Moreover, we also discuss the potential challenges and task in the future.

Key words: two-dimensional nanomaterial, perovskite, quantum confinement effect, luminescence
