Formation of cadmium oxide microcrystals, induced by Ar ion irradiation, on CdTe crystals is reported. The formation of the oxide crystallites is proved by the detection of a low temperature cathodoluminescence emission, centered at 2.2 eV. The emission is localized at the microcrystals on the irradiated CdTe surfaces. The compositional changes, after the irradiation, are studied by Energy Dispersive X-Ray spectroscopy and X-Ray Diffraction. The concurrent decrease of the near band edge CdTe luminescence emission and the increase of the 2.2 eV band intensity are correlated to the irradiation fluence. (C) 2012 Elsevier B.V.
