Localized surface plasmon resonances optically excited in metallic nanoparticles (NPs) produce beneficial thermal and nonthermal effects. Nonthermal effects, such as enhancing and localizing fields on subwavelength scales and photo-generating hot carriers, have been extensively exploited, while interest in highly localized photothermal heating is reviving. Both effects may work together synergistically, such as increasing the efficiency of a photocatalytic process, or they may work against each other, such as accelerating the desorption of analytes in surface-enhanced spectroscopy. To compare how these effects depend on the composition and size of the NP, we report a quantitative survey of thermal and nonthermal properties in the visible-solar (1.7–4.1 eV) and ultraviolet (3.1–6.2 eV) ranges for 19 metals, including conventional plasmonic materials (gold, silver, copper), an alkaline earth metal (magnesium), post-transition metals (aluminum, gallium, indium), and a wide variety of transition metals. Figures of merit that reflect the resistive losses and electric field enhancement factor of the NPs were used in this comparative analysis.

纳米等离子体光热加热和近场增强：19种金属的比较调查

在金属纳米粒子（NPs）中光学激发的局部表面等离子体激元共振产生有益的热效应和非热效应。非热效应，例如在亚波长范围内增强和定位场以及产生光的热载流子，已得到广泛利用，而对高度局部化光热加热的兴趣正在复苏。两种作用可以协同作用，例如增加光催化过程的效率，或者它们可以互相作用，例如加速表面增强光谱法中分析物的解吸。为了比较这些影响如何取决于NP的组成和大小，我们报告了对19种金属在可见光（1.7–4.1 eV）和紫外线（3.1–6.2 eV）范围内的热和非热性质的定量调查，包括传统的等离子材料（金，银，铜），碱土金属（镁），过渡后金属（铝，镓，铟）和多种过渡金属。在此比较分析中使用了反映NP的电阻损耗和电场增强因子的品质因数。
