抄録

We propose that nanostructures spontaneously generated by spinodal decomposition can be used as an efficiently luminescent material. The doping of Eu into GaN beyond the solubility limit forms EuN nanostructures, whose forms depend on the crystal growth method and conditions. The three-dimensional crystal growth generates the Dairiseki phase constructed of EuN quantum dots. These nanostructures are suitable for emission of red light and laser. The two-dimensional layer-by-layer crystal growth leads to the Konbu phase consisting of nanorods. The Konbu phase can be applied to the bottom-up construction of distributed feedback semiconductor lasers, which is currently built by the top-down nanotechnology such as photolithography.
