摘要
碳点(CD)是一种尺寸小于 10 纳米的新型纳米材料,因其出色的光学特性而备受关注。然而,尽管人们对这些材料在液态条件下的特性进行了广泛研究,但固态荧光和余辉方法的发展却相对缓慢。近年来,将光盘嵌入基质中可以防止聚集淬灭和抑制非辐射转变,从而实现固态荧光和余辉,这大大拓宽了光盘的研究和应用领域。从氢键、离子键、共价键和空间限制等方面来看,CD 与基质之间的相互作用能有效实现和改善 CD 的固态荧光和余辉效应。我们还总结了近年来基于基质中的光盘在光电子学、信息安全、传感、生物治疗和成像等方面的应用。最后,我们总结了基质中的光盘所面临的挑战和发展。
Recent advances in fluorescence and afterglow of CDs in matrices
Carbon dots (CDs) are novel nanomaterials with dimensions less than 10 nm that have attracted much attention due to their outstanding optical properties. However, the development of solid-state fluorescence and afterglow methods has been relatively slow, although the properties of these materials under liquid conditions have been extensively studied. In recent years, embedding CDs in a matrix has been shown to prevent aggregation quenching and inhibit nonradiative transitions, thus realizing solid-state fluorescence and afterglow, which has greatly broadened the research and application areas of CDs. In terms of hydrogen bonding, ionic bonding, covalent bonding and spatial confinement, the interactions between CDs and matrices can effectively realize and improve the solid-state fluorescence and afterglow effects of CDs. Recent applications of CDs in matrices in optoelectronics, information security, sensing, biotherapeutics and imaging are also summarized. Finally, we summarize the challenges and developments of CDs in matrices.
期刊介绍:
Nanoscale Horizons stands out as a premier journal for publishing exceptionally high-quality and innovative nanoscience and nanotechnology. The emphasis lies on original research that introduces a new concept or a novel perspective (a conceptual advance), prioritizing this over reporting technological improvements. Nevertheless, outstanding articles showcasing truly groundbreaking developments, including record-breaking performance, may also find a place in the journal. Published work must be of substantial general interest to our broad and diverse readership across the nanoscience and nanotechnology community.
