Due to the extinction of silicon from UV to near-infrared region, Mie resonances in silicon nanoparticles dramatically enhance the absorption of solar light. In experiment, silicon nanoparticles dispersed in water worked as excellent sunlight-heat transducers that efficiently harvest sunlight to accelerate heating and vaporization of water by nanoscale local heating. Our study opens up the potential of silicon nanoparticles in various solar-thermal applications.Journal Articleapplication/pdfhttp://hdl.handle.net/2115/72262https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/72262/1/ome6-2_640-648.pdf2159-3930Optical Materials Express626406482016enginfo:doi/10.1364/OME.6.000640© 2016 Optical Society of America].
