Mn-doped epitaxial ZnO thin films fabricated by molecular beam epitaxy were investigated. Well-structured blue and ultraviolet cathodoluminescence peaks were observed corresponding to the intra-d-shell transitions of Mn2+. Results showed that the quick decrement of isolated Mn2+ with increasing x is responsible for the severe suppression of the blue and ultraviolet luminescence.
