| 中文摘要:近年来, 纳米流体在太阳能光热利用方面极具前景。核壳结构纳米颗粒可以耦合多种材料的不同波段效应,调控光谱吸收波段, 实现太阳能的全光谱捕获吸收。将在长波具有高吸收的氧化锌掺杂镓 (GZO) 和在可见吸收好
的氮化钛 (TiN) 形成 GZO@TiN 核壳结构复合纳米颗粒, 可以发挥两种材料的优点。进一步, 从调节材料的尺寸和核壳材料出发, 探究 GZO@TiN 复合结构纳米流体的光谱特性变化规律。结果表明, 当 TiN 为核、GZO 为壳时, 可以
显现两种材料的共振效应；当 GZO 为核、TiN 为壳时, 长波区域的吸收峰消失。当浓度为 10?4 , 光学厚度为 10 mm时, TiN(壳)/GZO(核) 纳米流体的平均吸收率高达 100%。此工作对核壳结构复合纳米颗粒的光谱调控、吸收以及外壳、核心材料的选择有着一定的帮助。 |

| Abstract:In recent years, nanofluids have great prospects in solar thermal utilization. The nanoparticle core-shell structure can couple the different band effect of multiple materials, modulate the spectral absorption bands, and realize the full-spectrum capture absorption of solar energy. Formation of GZO@TiN core-shell composite nanoparticles by combining GZO with high absorption at long wavelengths
and TiN with high absorption in the visible region, can utilize the advantages of both materials. Further onwards, starting from the dimension and the core shell material, probing the changing regularity of spectral properties of GZO@TiN composite structured nanofluids. The results show that when TiN is the core and GZO is the shell, the resonance effect of the two materials can be revealed;
When GZO is the core and TiN is the shell, the absorption peak disappears in the long-wave region. The average absorption of TiN(shell)/GZO(core) nanofluids is up to 100% at a concentration of 10-4 and an optical thickness of 10 mm. This work is helpful for the spectral regulation and absorption as well as the selection of shell and core materials. |
