Recovering LSPR coloration in dried metal-nitride nanoparticle powders by sol–gel silica embedding

Shinji Noguchi, Tong Fang, Yuta Fujii, Kiyoharu Tadanaga

Sol–gel SiO 2 embedding recovers the LSPR-derived blue color of HfN nanoparticle powders that are otherwise black (Δ E 76 = 13.4); TiN, with its near-infrared LSPR, shows only a lightness-dominated change.
