Localized surface plasmon enhanced carbon dots based solar-blind ultraviolet photodetectors by Al nanoparticles

Localized surface plasmon resonance (LSPR) can enhance the optical field density around the nanostructure to improve devices’ light absorption. Aluminum nanoparticles (Al NPs) were introduced into solar-blind photodetectors with carbon dots (CDs) as a photosensitive material. It is found that by ins...
