On June 22, according to Japan's kyodo news agency reported that industrial university and Kyoto university in Tokyo, Japan's team 21, said in a news release that have developed rare red light-emitting semiconductor element does not use a high price. It is understood that the future is expected to use rich deposit of nitrogen made of nitrogen compounds on earth, with low cost applied to red light emitting diode (LED) and solar cells. Team would zinc nitride semiconductor alternate material set as the target object, lists 583 species list, through the super computer prediction and stability of crystalline structure, the sifting 21 species.

Industry on June 21, Tokyo university and Kyoto university research team says it has developed does not use the red light-emitting semiconductor higher rare elements. The graph is in the light of the new red glowing nitrides

In which researchers select a material suitable for use in a red LED, in 1200 degrees, about 50000 air pressure under the condition of synthesis. A red light is expected, the material in the sunlight that was found is expected to become a red LED material.

Leds have been successfully implemented using low nox blue and green, but red is not always practical application, is must use of rare elements and the problem of raw materials.

Industrial professor of computational materials science at the university of Tokyo big field scone, said: "this matter only applies rich calcium, zinc and nitrogen element can be made. In the future to study a simpler way of synthesis, promote the practical application."
