Blue-Green Luminescence in ZnO: Excitation by 20 eV Kinetic Energy Gas Phase Positive Ions.
Abstract
The characteristic blue-green luminescence of phosphor grade ZnO has been observed during the interaction of low kinetic energy (20 to 40 eV) gas phase positive ions with ZnO. The luminescence is attributed to hole formation and injection followed by radiative recombination. The light output has been examined as a function of ion kinetic energy and the ionization potentials of different neutral precursors. The light decays by a first order process with a 1/e lifetime of 6 microsec. The efficiency of ion excitation is estimated to be about 1 photon/30 ions for 40 eV kinetic energy He(+) ions. (Author)
