BU researcher invents cost-effective UV shield for LEDs

A PhD scholar at Barkatullah University has developed a nano-technology based invention to cut down the impact of UV rays from LED lights on human beings. Touseef Ahmad Para was awarded the 'best scientist award' for his zinc oxide technology at the Young Scientist Congress held by Madhya Pradesh Council of Science and Technology (MPCST) in Bhopal recently. His invention is cheaper than the costly phosphor that acts as a shield against UV rays, he said, adding that it will not only help check the impact of UV rays on humans but also reduce the cost of LEDs as more households and offices switch to LED.
