Such outstanding \u0394T values exclusively occur at wavelengths close to their localized plasmon resonances (\u0394T is significantly lower off resonance), and therefore the photothermal conversion of these nanoparticles is spectrally selective. The exceptional and spectrally selective temperature rise is demonstrated at near infrared (NIR) wavelengths, which prompts the use of Co and Ni helical nanoparticles in a wide range of photothermal applications including solar energy conversion, seawater desalination, catalysis, or nanomedicine.<\/p>\n<p>Further details are provided here<\/p>\n<a href=\"https:\/\/qmade.usal.es\/wp-content\/uploads\/sites\/36\/2024\/05\/Adv-Funct-Materials-2024-Delgado\u2010Notario-Enhanced-and-Spectrally-Selective-Near-Infrared-Photothermal-Conversion-in.pdf\" class=\"btn button btn-shortcode kad-btn kad-btn-primary\" id=\"kadbtn463\" target=\"_self\" style=\"background-color:#000;color:#FFF;\"onMouseOver=\"this.style.background='',this.style.color='#CDCDCD'\" onMouseOut=\"this.style.background='#000', this.style.color='#FFF'\">READ IT<\/a>","protected":false},"excerpt":{"rendered":"<p>We study the photothermal conversion in plasmonic nanohelices, unveiling how helical nanostructures made from metals with a notable interband activity -such as cobalt (Co) and nickel (Ni)- exhibit a remarkable temperature rise \u0394T up to \u22481000 K under illumination.
