There are several strategies to enhance photostability in nanomaterials:
Surface Coating: Applying a protective coating can shield nanoparticles from direct exposure to light, thereby reducing photodegradation. Materials like silica or polymers are commonly used for this purpose. Core-Shell Nanostructures: Creating core-shell structures where a photostable material forms the outer shell can significantly enhance the photostability of the core material. Doping: Introducing dopants into the nanomaterial can modify its electronic properties, making it more resistant to photodegradation. This approach is often used in quantum dots and nanowires. Ligand Exchange: Replacing the original ligands on the nanoparticle surface with more robust ones can improve photostability by reducing the reactivity of the surface.
