Luminescence Properties of Aluminoborate Compounds Activated with Europium Ion.

Abstract

Fluorescence material is not only used for a fluorescence lamp, but actives widely as a luminescence device of a display. BAM is a blue fluorescent substance that consists of aluminates, and gives strong luminescence. But BAM has a problem of heat degradation. Therefore, we remark the substance that consists of aluminoborates. In this study, Ca(Al_4-YB_Y)O₇ (Y=0.0∼1.0), which is the compound between CaAl₄O₇ and CaAl₃BO₇, were synthesized and their luminescence properties were measured.
