Abstract: Based on the 150°C and 1 h microwave-assisted hydrothermal reaction of Nd(NO3)3dissolved in deionized water with pH 10 adjusted by concentrated NH4OH solution, the phase and morphology of the product, characterized by XRD, SEM and TEM analyses, were specified as hexagonal Nd(OH)3nanorods 50 nm in diameter and 700 nm long, growing along the [0 0 1] direction. TGA analysis showed the evaporation of adsorbed water and dehydration of Nd(OH)3to synthesize the final pure Nd2O3product. With 500°C and 2 h calcination of the Nd(OH)3self-template precursor, Nd2O3nanorods were synthesized, retaining both the morphology and growth direction of the precursor. © 2012 Elsevier Ltd and Techna Group S.r.l.
