Material Advances for LED Quantum Dot Efficiency

Developing efficient and cost-effective ultraviolet light-emitting diodes (LEDs), especially in the deepultraviolet (UV-C) is a long-standing goal of the photonics community. UV-C LEDs are of particular interest and could replace gas discharge lamps, revolutionizing disinfection systems, provide water purification, and facilitate non-line-of-sight communication. In light of the on-going global pandemic due to COVID-19, implementation of a rapid surface disinfection method in which chemical cleaning is impractical or not as effective is of critical importance.
