Wurtzite ZnO is a wide band gap (Eg~3.37 eV) semiconductor with a large exciton binding energy of 60 meV at room temperature. It possesses several favorable properties,including good transparency, high electron mobility, and strong room-temperature luminescence. Those properties are used in several emerging applications in optoelectronics. In such application trivalent rare earth ions (RE3+) doped ZnO phosphors have been studied extensively during the last years, however the results are quite disappointing since the desired characteristic emission from RE3+ is weak under the indirect UV excitation of the ZnO host.
