Newly developed LEDs capable of producing ultraviolet light offer a cheaper, more stable, and more durable alternative by using a surface made of graphene.

“In a scientific first, researchers at the Norwegian University of Science and Technology (NTNU) successfully produce ultraviolet light using a surface made of graphene.
The process, which was long thought to be impossible, may soon lead to the creation of newer and better forms of lighting for general use.
“We’ve created a new electronic component that has the potential to become a commercial product,” study co-author Ida Marie Høiaas explained.
“It’s non-toxic and could turn out to be cheaper, and more stable and durable than today’s fluorescent lamps.”
The researchers hope that if they succeed in making the LEDs more efficient and affordable, the devices could eventually become commonplace in many people’s homes. This could help increase the market potential of their UV-emitting lights significantly.”
“The market for UVC-based products is expected to increase by $700 million over the next few years. The growing popularity of such devices and the eventual phasing out of mercury use could help the market increase by as much as 40 percent every year.
The NTNU researchers are hoping that their new LEDs could lead to better UVC products. They have already teamed up with tech company CrayoNano to develop an industrial platform for their UV technology. The firm is a spinoff of the university’s nano research team.
CrayoNano is looking at creating cheaper and more energy-efficient UVC LEDs that can one day replace fluorescent lights on the market.
The findings of the Norwegian University of Science and Technology study are featured in the journal Nano Letters.”
