The Chinese scientists have come closer to develop a faster wireless
communication channel that would be accessible in the next six years.
They have made progress in creating full-color emissive carbon dots
(F-CDs).
LiFi or Light Fidelity transfer data at a rapid pace
using visible light from LED bulbs. It is much faster than radio
wave-based Wi-Fi.
The latest research going on related to Li-Fi
uses rare earth materials to provide light, but Chinese experts have
come up with another option, F-CDs, a fluorescent carbon nanomaterial to
provide light. This method is safer, reliable and faster.
Qu
Songnan, an associate researcher at Changchun Institute of Optics, Fine
Mechanics, and Physics, the Chinese Academy of Sciences said, “Many
researchers around the world are still working on this. We were the
first to successfully create it using cost-effective raw materials such
as urea with simple processing.”
Qu informed that as the rare
earth has a longer lifespan it diminish the speed of Li-Fi transmission.
F-CDs, on the other hand, provides faster transmission of data.
New
nanomaterial introduced by Qu’s group of scientists can emit all light
visible to the human eye. This is an innovative development in
fluorescent carbon nanomaterial field. Qu further added that this
breakthrough this essential in the development of Li-Fi which he
anticipates will enter the market in next six years.
As per
statistics, Li-Fi can reach a speed of 50 gigabytes per second. So in
simplest terms, your movies can download in 0.3 seconds. I believe this
would define the importance of this discovery to a common man.
