Scientists are optimistic about the prospect of replacing the harmful effects of ultraviolet light with a much more beneficial, even if the effect is limited to specific parts of the body.
The team at the Indian Institute of Technology, Bangalore (IIT-B), said they would begin work on a process that would allow for “super-bright” and “bright” images of the planet’s surface that are brighter than that of our sun.
This could pave the way for more efficient use of sunlight for energy, and for the development of devices that would make solar energy more useful in a range of applications, they said in a press release.
Irradiance from the sun, which we can measure in wavelengths from 400nm to 700nm, is the result of electrons reacting with the atoms of hydrogen and helium in the Earth and other planets.
These reactions cause electrons to move away from the atoms and onto the surrounding gas.
The electrons, which are called photons, are the same wavelength that is used by our eyes to detect light.
This wavelength can be measured from the Earth by measuring the difference in light intensity between different wavelengths.
The new technique would use “optical fluorescence” to “transcribe” the light from the electron’s path through the gas and into the skin of the observer.
The resulting image would be “bright enough” to be seen from space, the researchers said.
The team’s proposal is similar to the technique that was used to create the “ultraviolet fluorescence,” which is what is currently used for the production of “visible light” in smartphones and computers.
However, the new approach will not be used in everyday life, they added.
“In the future, we may find that infrared fluorescence is less useful than the visible light that we use in everyday objects,” said Dr Anupam Gupta, who led the research.
Scientists are now working on a method to produce the light that will help them “detect the molecules and molecules of our atmosphere and also the atmosphere of other planets,” Dr Gupta said.
