Optical property theoretical study and mild-temperature synthesis of (Ga,Zn)N nanocrystals

Wurtzite GaN and (Ga,Zn)N nanocrystals about 8-20 nm were synthesized at mild temperature. Optical properties were analyzed theoretically by means of quantum chemical method. Zn dopant increases activity of GaN in visible region. White light can be produced by mixing the strong blue and yellow emission lines.
