Abstract

Abstract

La1.6(MoO4)3:Eu0.43+ nancrystal is synthesized by combustion method and the interaction between the phonon-dopant-lattice and luminescence properties of this nanocrystal are investigated. It is shown by X-ray diffraction that the powders are crystallized in a single phase annealed at 500~900 ℃. It is found that the excitation of the Mo6+-O2- charge transfer band(CTB) can result in the emissions of Eu3+ ion, which indicates that energy transfer takes place from CTB to Eu3+ ions. Two one-phonon sidebands locate at 1=469 nm and 2=426 nm in the excitation spectra which are due to Mo=O and MoOMo expand and contract vibration modes, respectively, with phonon energies of 1 202 cm-1 and 767 cm-1. The Huang-Kun factors S1=0.055 and S2=0.037 describing the interaction intensity between phonon and lattice are determined. The optical properties of La1.6(MoO4)3:Eu0.43+ would be able to provide the experimental foundation to reveal the properties of high conductivity and negative thermal expansion(NTE) with the trivalent ions.
