The fabrication of photoluminescent Ti₃C₂ MXene quantum dots (MQDs) by a facile hydrothermal method is reported, which may greatly extend the applications of MXene‐based materials. Interestingly, the as‐prepared MQDs show excitation‐dependent photoluminescence spectra with quantum yields of up to ≈10% due to strong quantum confinement. The applications of MQDs as biocompatible multicolor cellular imaging probes and zinc ion sensors are demonstrated.

用于多色细胞成像的光致发光Ti3C2 MXene量子点

据报道，通过简便的水热法可制备光致发光的Ti ₃ C ₂ MXene量子点（MQDs），这可能会大大扩展MXene基材料的应用范围。有趣的是，由于强的量子限制，所制备的MQDs显示出与激发有关的光致发光光谱，其量子产率高达约10％。展示了MQD作为生物相容性多色细胞成像探针和锌离子传感器的应用。
