Papers by Keyword: SrAl₂O₄:Eu Film

Abstract: Highly oriented SrAl2O4:Eu film had been deposited on a quartz glass using the RF sputtering method. The fabricated film displayed fiber-texture with the (031) orientation. The surface of the film was smooth and compact. In addition, under the UV excitation, the film emitted green light. After the removal of UV excitation, a long afterglow phenomenon could be observed from this film. The important point of this study was that SAOE film displays strong adhesion and high green triboluminescence (Tribo-L). Such properties made the films be a potential candidate as stress indicators.

Abstract: SrAl2O4:Eu films on an inconel 600 substrate with good adhesion were successfully prepared by the radio frequency sputtering method. The crystallinity and surface morphology of the SrAl2O4:Eu films were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and atomic force microscope (AFM). The films exhibited an intensively green photoluminescence (PL) and high triboluminescence (Tribo-L) intensity.
