摘要

Nanostructures of InVO4 and InVO4:Eu3+ were synthesized through a hydrothermal method with a post annealing process. The morphology and luminescence properties of InVO4:xEu(3+) can be modulated by Eu3+ ion doping concentration. SEM and (HR)TEM studies indicated that different sizes of nanoparticles were obtained when the Eu3+ ion concentration ranged from 2 mol% to 30 mol%, and middle-concave nanodisks or nanoparticles with different sizes were obtained with the Eu3+ ion concentration ranging from 35 mol% to 45 mol%. Luminescence property studies indicated that the photoluminescence emission originated both from VO43- and Eu3+, and the emission of VO43- was blue shifted, affected by the doped Eu3+ ions. The CIE chromaticity diagram of Eu3+-doped indium vanadate exhibited green, blue-green, red, giving especially white light emission.
