The nanocrystals Er2O3 were prepared by using a combustion method with Schiff base as a chelating agent. The Er(Ⅲ) coordanation compound of Schiff base, obtain
A series of compounds, La2/3-xLi3xMoO4, were first prepared. Their structures are tetragonal scheelites with the cationic defects. The cell parameters a, c and
