Abstract
The f-->f transition emission of Eu2+ in LiAl5O3 and alpha - Al2O3 is found for the first time, disappearing of the f-->f transition emissio m of Eu2+ and there existing a new band emission in mixture phases of alpha-Al2O3 and gamma-Al2O3. The experimental results are discussed in detail by crystal structure data of hosts and theory of crystal field and covalence. Partial charge of Eu2+ and ionic percentage of Eu-O(F) and M O(F) in hosts are calculated by Sanderson's theory, a content e xplanation of the experimental phenomena being obtained.
