Abstract
SrAl2 O4 activated with Eu phosphors has been known to exhibit highly bright and long-lasting phosphorescence without radioactive materials. In this paper, SrAl2 O4 :Eu thin films have been successfully deposited on Si(100) or graphite substrate by using an intense pulsed ion-beam evaporation technique. The results of X-ray diffraction and photoluminescence suggest that SrAl2 O4 :Eu thin films which has a polycrystalline structure can be produced in vacuum, without substrate heating and annealing. The composition and morphology of the films have been analyzed by Rutherford backscattering and scanning electron microscope. From RBS analyze, we have obtained good stoichiometry between the target and the films prepared.
