Alumina doped with La and Ce was prepared by using the sol-gel technique. The doping concentrations were alternatively 2 and 5 wt% for each element. Samples were characterized as a function of temperature by using X-ray powder diffraction and FTIR spectroscopy. MAS-NMR studies showed that lanthanum
## Abstract Nanocrystalline particles of Co^2+^doped lithium aluminate (Co^2+^:LAO) and Ni^2+^โdoped lithium aluminate (Ni^2+^:LAO) were synthesized by solโgel method. The crystalline nature and particle size of the samples were characterized by Xโray diffraction analysis (XRD). The morphology and
