Photoluminescent Ti3C2 MXene Quantum Dots for Multicolor Cellular Imaging

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 ≈1...

Zusammenfassung: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.
