Abstract

Abstract:

Luminescent materials of rhombus CeO₂ was prepared by hydrothermal synthesis method.The crystal structure,morphology,charge state,crystallinity,optical and photoluminescence properties of rhombus CeO₂ were characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM）,UV-visible spectrophotometer（UV-Vis）,selected area electron diffraction（SAED） and photofluorescence spectrophotometer（PL）.XRD and XPS analysis indicated that there is a large amount of adsorbed oxygen in CeO₂ luminescent material,and the oxygen vacancy concentration of this material was 1.723 7×10 ²⁰ cm ^-3.Optical properties analysis showed that CeO₂ luminescent materials have strong light absorption capacity below 400 nm,and its optical band gap（E_g） value was 3.19 eV.Photoluminescence spectrum analysis showed that four fluorescence emission peaks at 460,470,540,580 nm can be observed under the excitation wavelength of 202 nm,and their chrominance coordinate was（0.188,0.243）.Based on the experimental results and theoretical analysis,the corresponding photolumines-cence mechanism was proposed.

Key words: CeO₂, hydrothermal method, adsorbed oxygen, oxygen vacancy, optical band gap, photoluminescence mechanism
