A research team from the Indian Institute of Technology<\/a>, Madras, has synthesized a white Light<\/a> emitting crystal in the laboratory that can be used for energy saving and long-lasting LED (light emitting diode) lights and display. The team synthesized a crystalline material called halide-perovskites, which emitted an intense white light when its structure was distorted.<\/p>\n

This indigenously developed bright white light emitter can potentially replace the conventional highcost material and phenomenally save the energy cost per lumens.<\/p>\n

According to the researchers, halide-perovskites have extraordinary optoelectronic (light-emitting) properties and high light-to-current conversion efficiencies. The researchers said the distorted perovskite can be used independently as a white light emitter or as a phosphor, a solid material that emits light, in combination with blue LEDs to produce white light.<\/p>\n

The distorted material also showed high stability under ambient conditions. The emission of intense light and stability make them useful in long-lasting, energy-saving lighting applications. Besides general lighting, white LEDs can be used in liquid crystal display backlights, display mobile lighting, and medical and Communication<\/a> equipment.<\/p>\n

Energy-efficient LEDs, which replaced energy-inefficient incandescent lamps, are available in almost all colours, but white LEDS are a recent development where specialised techniques were used to produce white light. Blue LED is coated with yellow phosphor, a light emitting solid material, and blue, green and red LEDs are combined to produce white light. The use of such indirect techniques can cause a loss of efficiency forcing researchers to look for material that can directly emit white light.<\/p>\n","protected":false},"excerpt":{"rendered":"
