Lighting 'will Be Revolutionised' By Semiconductor Nanotechnology

Semiconductor technology will help to "revolutionise" the lighting sector, which will see CFLs be replaced.
Light emitting diodes (LEDs) based on nanotechnology will "revolutionise" lighting and replace compact fluorescent lamps (CFLs), it has been claimed.

The semiconductor devices use nano phosphors which have better scattering and illuminating capacity compared to CFLs and their energy-efficient benefits have resulted in New Delhi currently funding a project on solid state lights based on nanotechnology, the Times of India reported.

LEDs are multilayered semiconductors which allow nano phosphors to stick on the surface, which is how they scatter light better than CFLs.

Professor Avinash Pandey, head of the department of atmospheric and ocean science at the University of Allahabad, told the newspaper that LEDs have greater longevity and better colour refractions than more traditional lighting.

"The nanomaterial-based approach for eco-friendly and energy-efficient energy is the need of [the] hour for ensuring sustainable development," he added.

Using LEDs in exit signs and traffic signals has proved to be effective because of their long life, visibility and brightness, the Lighting Research Centre recently noted.ADNFCR-2855-ID-19442354-ADNFCR
