IIT-M researchers develop white light emitter for use in LEDs
Researchers at the Indian Institute of Technology-Madras (IIT-M) have successfully developed a white light emitter for use in LEDs which replaced the energy-inefficient incandescent lamps in lighting and display applications. Conventional LED materials cannot emit white light and specialised techniques such as coating blue LED with yellow phosphor and combining blue, green,
