Korean scientists claim that they have developed the world's first LED with a pure white light. If they develop will be able to repeat in other laboratories, and then put into mass production, the LEDs can be fairly quickly replaced by compact fluorescent lamps (CFL), previously replaced the colored bulb. LEDs use far less energy than CFL, but so far they have not been as bright as could not create white LEDs.

Under the leadership of Park, professor of Seoul National University, working in the field of organic materials for photonics, a group of scientists managed to obtain a molecule with two emitting sites, one of which emits an orange light, and the second ─ blue, which gives white visible light. Preliminary tests showed that the new LED-molecule effective, have a stable color and can be replicated in other laboratories. Park said that it is not only the world's first white LED, but also the first dual LED, each molecule of which consists of two no interacting with the intermolecular proton transfer in the excited state.

Scientists have so far hampered the emergence of ready-called timing devices on the basis of the new LEDs.
