Mono-disperse MMoO3·2H2O (M = Mn, Co, Ni) compound nanocrystals: Syntheses, characterization and luminescent properties

Mono-disperse MMoO3·2H2O (M = Mn, Co, Ni) compound nanocrystals were synthesized by a low-temperature hydrothermal reaction route using N2H4·H2O as a reduction reagent as well as a structure-directed reagent. The physical characterizations were carried out by TGA, XRD, XPS, SEM and Photo RF. The data of XRD indicate a single phase of monocline symmetry. Nanostructures of MMoO3·2H2O (M = Mn, Co, Ni) samples in zero, one or two dimensions were observed from SEM images, respectively. Furthermore, MMoO3·2H2O are luminescent, which is different from composite oxides with ordinary structure.
