Nanophotonics is an important branch of modern optics dealing with light–matter interaction at the nanoscale. Nanoparticles can exhibit enhanced light absorption under illumination by light, and they become nanoscale sources of heat that can be precisely controlled and manipulated. For metal nanoparticles, such effects have been studied in the framework of thermoplasmonics, which, similar to plasmonics itself, has a number of limitations. Recently emerged all-dielectric resonant nanophotonics is associated with optically induced electric and magnetic Mie resonances, and this field hasdeveloped very rapidly over the past decade. As a result, thermoplasmonics is being complemented by all-dielectric thermonanophotonics with many important applications such as photothermal cancer therapy, drug and gene delivery, nanochemistry, and photothermal imaging. This review paper aims to introduce this new field of non-plasmonic nanophotonics and discuss associated thermally induced processes at the nanoscale.

全介电热纳米光子学

纳米光子学是现代光学的一个重要分支，处理纳米尺度的光-物质相互作用。纳米粒子在光的照射下可以表现出增强的光吸收，并且它们成为可以精确控制和操纵的纳米级热源。用于金属纳米颗粒，这样的效果进行了研究，框架thermoplasmonics，其中，相似的等离子体本身，有许多限制的。最近出现的全介电共振纳米光子学与光感应电和磁 Mie 共振相关，并且该领域在过去十年中发展非常迅速。因此，热等离子体正在由全介电热纳米光子学补充具有许多重要的应用，如光热癌症治疗、药物和基因传递、纳米化学和光热成像。这篇综述论文旨在介绍非等离子体纳米光子学的这一新领域，并讨论相关的纳米级热诱导过程。
