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.
