Abstract

In this paper, Bi2MoO6:Eu3+ phosphors were successfully synthesized via a facile, efficient hydrothermal synthesis process followed by a further calcination treatment without using any surfactants. The samples were analyzed by XRD, UV-vis absorption spectroscopy, photoluminescence (PL) and decay curve measurements. XRD patterns reveal that all the diffraction peaks could be indexed to well-crystallized orthorhombic structures. UV-visible diffuse reflection spectra of the prepared Bi2MoO6 and Bi2MoO6:Eu3+ indicate that they had absorption in the UV-light region. The luminescence spectra showed that Bi2MoO6:Eu3+ phosphors can be effectively excited by UV light (328 nm), and exhibited strong red emission around 613 nm attributed to the Eu3+ 5D07F2 transition. Effects of Eu3+ concentration on lattice constants and PL were presented.
