All-inorganic perovskite nanocrystals (NCs) have emerged as a new generation of low-cost semiconducting luminescent system for optoelectronic applications. The room-temperature photoluminescence quantum yields (PLQYs) these NCs in the green and red spectral range approach unity. However, their PLQYs violet are much lower, an insightful understanding such poor performance remains missing. We report general strategy synthesis all-inorganic violet-emitting with near-unity through engineering...
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.
