HR-STEM images of Ti-doped nano MgAl2O4; a. The image shows Al3+ vacancy and Ti4+ dopant in the vicinity with Fourier transformation of the image. b The magnified image in red box of (a) and Al3+vacancy is revealed from STEM image with a corresponding contrast intensity, inset of (b). c The contrast intensity, inset of (c), confirms that Ti4+ dopant occupies an Al site. The arrows indicate the locations of Al vacancy and Ti in Al site, respectively
