Abstract

Introducing nitrogen vacancies into gallium nitride nanoparticles might allow tuning optoelectronic properties. Comparing experimental and theoretical data establishes that an observed broad chemical shift distribution in 71Ga MAS NMR spectra results from chemical inhomogeneities at the atomic level within GaN nanoparticles, which can be correlated with the intensity of blue band edge related photoluminescence.
