Abstract Phosphors emitting visible and near-infrared persistent luminescence have been explored extensively owing to their unusual properties commercial interest in applications such as glow-in-the-dark paints, optical information storage, vivo bioimaging. However, no phosphor that features emissions the ultraviolet C range (200–280 nm) has known exist so far. Here, we demonstrate a strategy for creating new generation of exhibits strong emission with an initial power density over 10...
Abstract The localized surface plasmon resonances (LSPR) effect makes W 18 O 49 an effective visible and near‐infrared (NIR) light antenna to realize full‐spectrum solar‐light driven photocatalysis, yet the precise origin remains elusive.
