摘要
Nanocrystalline Y 2O 3,CeO 2,Nd 2O 3,Pr 6O 11 and Sm 2O 3 were prepared by glycine nitrate combustion synthesis and the chemical stability of nanocrystalline Nd 2O 3,Pr 6O 11 and Sm 2O 3 in moisture had also been studied.The IR analysis on nanocrystalline Y 2O 3 indicated that with the decrease of particle size,the IR absorption peak due to Y O stretching vibration shifted red,together with the expansion of the IR absorption peak.
