- Abstract
Ti-doped nano MgAl2O4 for white emission was synthesized by combustion method. Extrinsic Schottky defects, Al vacancies and Ti4+ dopant in Al sites, which are considered to be responsible for bluish-white emission, were observed by STEM on the surface of Ti-doped nano MgAl2O4powder. The stabilities of the Schottky defect associates, (TiAl
·–VAl′′′)′′, were demonstrated by DFT calculation. The emission behavior was interpreted with these results.
