Abstract

Here, we fabricated an oxygen-deficient WO_3−x crystalline/amorphous homojunction with a strong and tunable localized surface plasmon resonance (LSPR) absorption and realized selective solar modulation over infrared light by controlling the experimental parameters. The homojunction shows good LSPR stability in photochromic cycles, which paves the way to control LSPR applications.
