The effects of low-energy irradiation by light ions (H and He) on the properties of In-rich In(x)Ga(1-x)N alloys are investigated by optical and structural techniques. H-irradiation gives rise to a remarkable blue-shift of light emission and absorption edge energies. X-ray absorption measurements and first-principle calculations address the microscopic origin of these effects.
