[13a-2R-8] Crystallographic and Spectroscopic Anomalies in Zn Doped CoAl2O4 Spinel Oxides
Keywords:spinel oxide,Spectroscopic characteristics,fluorescence
Correlation between crystallograpic change and the spectroscopic characteristics were investigated for the sample series of (Co,Zn)Al2O4. Then, some interesting phenomena were found in this study. Especially, fluorescence phenomenon is important, and it is considered relating to the property of Co2+ at B site of the spinel structure. It is worth studying, since this material doesn't have rare earth elements.
