摘要

对分散在二氧化硅中的不同半径和壳厚的新型氧化镍-镍纳米壳（NSs）在 200 纳米到 5000 纳米的紫外线、可见光和红外线光谱范围内的光学特性进行了理论研究。NiO-Ni NSs 在所述光谱范围内已确定的出色的吸收（消光）光谱可调性和高吸收特性非常适合用于各种光热和激光高温技术，包括光热转换、太阳能热能、激光纳米医学等方面的应用。

Significant tunability and absorptivity of plasmonic NiO-Ni nanoshells dispersed in silica in visible and infrared optical spectra

A theoretical study of the optical properties of new NiO-Ni nanoshells (NSs) with different radii and shell thicknesses dispersed in silica was carried out in a wide range of ultraviolet, visible and infrared optical spectra from 200 nm to 5000 nm. The established remarkable tunability of absorption (extinction) spectrum and the high absorption properties of NiO-Ni NSs in the presented spectral ranges are very interesting for use in various photothermal and laser high-temperature technologies, including applications in light-to-heat conversion, solar thermal energy, laser nanomedicine and others.
