Nickel oxide (NiO) is one of the very few p -type semiconducting oxides, the study of which is gaining increasing attention in recent years due to its potential applicability in many emerging fields of technological research. Actually, a growing number of scientific works focus on NiO-based electrochromic devices, high-frequency spintronics, fuel cell electrodes, supercapacitors, photocatalyst, chemical/gas sensors, or magnetic devices, among others. However, less has been done so far in the development of NiO-based optical devices, a field in which this versatile transition metal oxide still lags in performance despite its potential applicability. This review could contribute with novelty and new forefront insights on NiO micro and nanostructures with promising applicability in optical and optoelectronic devices. As some examples, NiO lighting devices, optical microresonators, waveguides, optical limiters, and neuromorphic applications are reviewed and analyzed in this work. These emerging functionalities, together with some other recent developments based on NiO micro and nanostructures, can open a new field of research based on this p -type material which still remains scarcely explored from an optical perspective, and would pave the way to future research and scientific advances.

基于 NiO 微纳米结构的新兴光学和光电应用方法

氧化镍 (NiO) 是极少数 p 型半导体氧化物之一,由于其在许多新兴技术研究领域的潜在适用性,近年来对其研究越来越受到关注。实际上,越来越多的科学工作关注基于 NiO 的电致变色器件、高频自旋电子学、燃料电池电极、超级电容器、光催化剂、化学/气体传感器或磁性器件等。然而,迄今为止,在基于 NiO 的光学器件的开发方面做得很少,尽管这种多功能的过渡金属氧化物具有潜在的适用性,但在该领域的性能仍然落后。这篇综述有助于对 NiO 微纳米结构的新颖性和新的前沿见解做出贡献,在光学和光电器件中具有广阔的应用前景。作为一些例子,在这项工作中回顾和分析了 NiO 照明设备、光学微谐振器、波导、光学限制器和神经形态应用。这些新兴的功能以及基于 NiO 微纳米结构的其他一些近期发展,可以开辟基于这种 p 型材料的新研究领域,从光学角度来看,该材料仍然很少被探索,并将为未来的研究和发展铺平道路。科学进步。
