Abstract

The fluorescence of divalent europium is important in blue luminescence such as that used in plasma displays. This research aimed to develop a useful method for producing divalent europium fluorescence. Anodic alumina was used as a support material and the conditions under which divalent europium is stable were examined. The design of material by DV-Xα molecular orbital simulation and the structure of aluminum oxide in which divalent europium ions are stable were examined. The electroluminescence of divalent europium was confirmed.
