Mossbauer study of amorphous Al2O3:Eu3+

摘要

We report a luminescence study of a newly synthesized material Al2O3:Eu3+ [1]. An X-ray diffraction study demonstrated crystalline characteristics while a luminescence study demonstrated an amorphous characteristic of this material. Such disagreement could result from incomplete sample crystallization. It is important to study the temperature effect on the degree of crystallization and to obtain a better understanding of the structure of this new luminescent material. In this study, we present the results of a Mossbauer study to investigate the structural details of the amorphous Al2O3:Eu2+.
