研究目的

To present recent advances in luminescent nanomaterials for sensing water and relative humidity, highlighting their advantages, detection strategies, and discussing challenges and opportunities in the field.

研究成果

Luminescent nanosensors based on nanomaterials like L-CuNCs, CQDs, MOFs, COFs, and others show high selectivity, sensitivity, rapidity, simplicity, and low cost for water and RH detection, with some demonstrated practical applications. Future work should focus on developing new nanomaterials with better properties, improved stability, novel mechanisms, and broader real-world applications, including potential use in outer space exploration.

研究不足

The review identifies challenges such as the need for simpler and more environmentally friendly synthesis methods, improved stability of nanoprobes, development of novel detection mechanisms to avoid background interference, and demonstration of practical applications in real samples. It also notes issues like the toxicity of certain materials (e.g., Pb2? in perovskites).
