胶体半导体纳米晶体(SCNC)或更广泛地说,胶体量子纳米结构构成了研究尺寸和维度效应的杰出模型系统。它们的纳米尺度导致量子限制效应,使其光学和电子特性的调谐。因此,具有窄光致发光光谱、宽吸收光谱和出色光稳定性的发射颜色控制,以及通过控制其表面化学而实现的化学加工性,导致SCNC作为当前和下一代显示器的杰出材料出现。在这篇综述中,我们介绍了SCNCs的基本化学和物理性质,然后描述了不同胶体量子纳米结构用于显示应用的优势。公开的挑战,就其光学活性的解决。描述了利用SCNC的光致发光和电致发光显示场景。
Colloidal semiconductor nanocrystals (SCNCs) or, more broadly, colloidal quantum nanostructures constitute outstanding model systems for investigating size and dimensionality effects. Their nanoscale dimensions lead to quantum confinement effects that enable tuning of their optical and electronic properties. Thus, emission color control with narrow photoluminescence spectra, wide absorbance spectra, and outstanding photostability, combined with their chemical processability through control of their surface chemistry leads to the emergence of SCNCs as outstanding materials for present and next‐generation displays. In this Review, we present the fundamental chemical and physical properties of SCNCs, followed by a description of the advantages of different colloidal quantum nanostructures for display applications. The open challenges with respect to their optical activity are addressed. Both photoluminescent and electroluminescent display scenarios utilizing SCNCs are described.
