Ultrathin Bi2MO6 (M=W, Mo) nanoplates were synthesized by a simple hydrothermal method. SEM, EDS and XRD were used to investigate the morphologies and compositions of the samples from BiONO3 nanoplates along with some nanoparticles, to precursory Bi2WO6 nanoplates and Bi2MoO6 nanoparticles, and to final Bi2MO6 nanoplates. The possible formation mechanism of products was proposed. The experimental results exhibited that Bi2MO6 nanoplates had stronger light adsorption in ultravioletvisible range. Bi2MO6 nanoplates were useful host for rare earth ions, Eu3+was successfully doped in Bi2MO6 nanoplates and an energy efficiently transferred from Bi3+ to Eu3+, displaying intense red color under ultraviolet (UV) light excitation. The morphologies of products kept constant after doping. It is suggested that Bi2MO6:Eu nanoplates have promising application in fluorescent mark. (C) 2012 Chinese Materials Research Society.
