Abstract:
Water scarcity is a growing challenge, necessitating the development of innovative desalination techniques that are energy-efficient and environmentally sustainable. Conventional desalination methods such as reverse osmosis and thermal distillation suffer from high energy demands and operational limitations. This review explores photoluminescence-assisted desalination, an emerging technique that leverages photoluminescent nanomaterials to facilitate salt removal through photothermal heating, ion-selective interactions, and photocatalytic precipitation. Key materials—including lanthanide-doped phosphors (Eu³⁺-Y₂O₃, Tb³⁺-Gd₂O₃), carbon quantum dots (CQDs), graphitic carbon nitride (g-C₃N₄), and semiconductor-based nanostructures (ZnO, TiO₂, CdS)—are examined for their role in desalination. The practical applications of this method in sustainable agriculture and drinking water production are also discussed, highlighting its potential for real-world implementation. The review concludes with insights into current challenges and future directions for scaling up photoluminescence-assisted desalination systems.
