英文摘要Hydrothermal syntheses of GdAlO3 and GdAlO3:Eu3+ microcrystals were reported, and the effects of reaction temperature and NaOH concentration on the formation of GdAlO3 were discussed. The crystal structure, morphologies, composition and luminescent properties of the obtained samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDX) and photoluminescence (PL) spectra. XRD results indicate all X-ray diffraction patterns of the synthesized samples were indexed by an orthorhombic system with the space group of Pbnm(62#). SEM image exhibits the uniform rectangular shapes of the as-synthesized GdAlO3:0.05Eu(3+) microcrystals with the sizes of about 3-6 mu m. The PL spectrum shows that the main emissions of GdAlO3:Eu3+ are attributed to the D-5(0) -> F-7(1) and D-5(0) -> F-2(2) transitions of Eu3+. The host absorption of GdAlO3:Ee in VUV region is weaker than that of the O2- -> Eu3+ charge transfer band. (C) 2014 Elsevier B.V. All rights reserved.
