As a new solution‐processable laser material, carbon dots (CDs) offer advantages of non‐toxicity, low‐cost, and high‐stability, which are conducive to the sustainable development of miniaturized lasers. Full‐color CDs (FC‐CDs) with bright‐blue, green, yellow, red, deep‐red, and near‐infrared (NIR) fluorescence are prepared. Their photoluminescence emission ranges from 431 to 714 nm. The FC‐CDs show...
In treatment of hypoxic tumors, oxygen‐dependent photodynamic therapy (PDT) is considerably limited. Herein, a new bimetallic and biphasic Rh‐based core–shell nanosystem (Au@Rh‐ICG‐CM) is developed to address tumor hypoxia while achieving high PDT efficacy. Such porous Au@Rh core–shell nanostructures are expected to exhibit catalase‐like activity to efficiently catalyze oxygen generation from endogenous...
