Preparation of Monodispersed Eu3+:CaMoO4 Nanocrystals with Single Quasihexagon

This paper reports the preparation of Eu3+:CaMoO4 nanocrystals by the microemulsion-mediated hydrothermal method. The synthesized Eu3+:CaMoO4 nanocrystals were characterized by XRD, transmission electron microscopy, high-resolution transmission electron microscopy, excitation, and emission spectra. The result shown that Eu3+:CaMoO4 nanocrystals with sizes of 40–90 nm exhibited a monodispersed and single quasihexagon. Eu3+:CaMoO4 nanocrystals exhibit a strong red fluorescence at 614 nm. This result may bring opportunity for the development of the other nanocrystals.
