Abstract

The core-shell structured SiO{sub 2}-Lu{sub 2}O{sub 3}:Ln{sup 3+} particles were realized by coating the Lu{sub 2}O{sub 3}:Ln{sup 3+} phosphors onto the surface of non-aggregated, monodisperse and spherical SiO{sub 2} particles by the Pechini sol-gel method. The as-synthesized products were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray (EDX) spectra, scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), photolumiminescence (PL), and low-voltage cathodoluminescence (CL). The results indicate that the 800 Degree-Sign C annealed sample consists of crystalline Lu{sub 2}O{sub 3} shells and amorphous SiO{sub 2} cores, in spherical shape with a narrow size distribution. The as-obtained particles show strong light emission with different colors corresponding to different Ln{sup 3+} ions under ultraviolet-visible light excitation and low-voltage electron beams excitation, which have potential applications in fluorescent lamps and field emission displays. - Graphical Abstract: Representative SEM and TEM images of the core-shell structured SiO{sub 2}-Lu{sub 2}O{sub 3}:Eu{sup 3+} particles; CIE chromaticity diagram showing the emission colors for SiO{sub 2}-Lu{sub 2}O{sub 3}:Ln{sup 3+}; Multicolor emissions of SiO{sub 2}-Lu{sub 2}O{sub 3}:Ln{sup 3+} particles.

Journal Article Wang, H; Yang, J; Zhang, C; ... - Journal of Solid State Chemistry

Spherical SiO{sub 2} particles have been coated with rare earth oxide layers by a Pechini sol-gel process, leading to the formation of core-shell structured SiO{sub 2}-RE{sub 2}O{sub 3} (RE=rare earth elements) and SiO{sub 2}-Gd{sub 2}O{sub 3}:Ln{sup 3+} (Ln=Eu, Tb, Dy, Sm, Er, Ho) particles. X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), photoluminescence (PL), and cathodoluminescence spectra as well as lifetimes were used to characterize the resulting SiO{sub 2}-RE{sub 2}O{sub 3} (RE=rare earth elements) and SiO{sub 2}-Gd{sub 2}O{sub 3}:Ln{sup 3+} (Eu{sup 3+}, Tb{sup 3+}, Dy{sup 3+}, Sm{sup 3+}, Er{sup 3+}, Ho{sup 3+}) samples.

Luminescence properties of core-shell structured SiO{sub 2}-CaMoO{sub 4}:Eu{sup 3+} phosphor

Journal Article Xiaoxia, Ju; Yuling, Yang; Wulin, Li; ... - Journal of Solid State Chemistry

Uniform SiO{sub 2}-CaMoO{sub 4}:Eu{sup 3+} red phosphor has been synthesized by sol-gel method, and its luminescence properties have been studied by fluorescence spectrometer. The structure and morphology of the SiO{sub 2}-CaMoO{sub 4}:Eu{sup 3+} red phosphor have been investigated by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and FT-IR spectrometer. Results indicate that phosphor particles have a core-shell structure and the thickness of the SiO{sub 2}-shell is about 60 nm. In addition, the luminescent intensity of SiO{sub 2}-CaMoO{sub 4}:Eu{sup 3+} red phosphor has been greatly enhanced with respect to CaMoO{sub 4}:Eu{sup 3+}more »« less

Uniform AMoO{sub 4}:Ln (A=Sr{sup 2+}, Ba{sup 2+}; Ln=Eu{sup 3+}, Tb{sup 3+}) submicron particles: Solvothermal synthesis and luminescent properties

Journal Article Piaoping, Yang; Chunxia, Li; Wenxin, Wang; ... - Journal of Solid State Chemistry

Rare-earth ions (Eu{sup 3+}, Tb{sup 3+}) doped AMoO{sub 4} (A=Sr, Ba) particles with uniform morphologies were successfully prepared through a facile solvothermal process using ethylene glycol (EG) as protecting agent. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectra (XPS), Fourier transform infrared spectroscopy (FT-IR), photoluminescence (PL) spectra and the kinetic decays were performed to characterize these samples. The XRD results reveal that all the doped samples are of high purity and crystallinity and assigned to the tetragonal scheelite-type structure of the AMoO{sub 4} phase. It has been shown that the as-synthesized SrMoO{sub 4}:Ln andmore »« less
