title: Coating of Y2O3:Eu3+ particles with alumina by a humid solid state reaction at room temperature.
abstract: Humid solid state reaction at room temperature was utilized for the first time to coat Y(2)O(3):Eu(3+) particles with alumina. The particles were studied with an X-ray photoelectron spectrometer (XPS), a scanning electron microscope (SEM), and an energy dispersive spectrometer (EDS). XPS results show that the yttrium and europium contents are decreased and that the aluminum content is the highest except for that of oxygen after coating. SEM and EDS results show that particles are coated with a thin shell of alumina.
