Title: Fabrication and luminescence properties of one-dimensional ZnAl{sub 2}O{sub 4} and ZnAl{sub 2}O{sub 4}: A{sup 3+} (A = Cr, Eu, Tb) microfibers by electrospinning method

Abstract

Graphical abstract: Different color emission can be realized in one-dimensional ZnAl{sub 2}O{sub 4}: A{sup 3+} (A = Cr, Eu, Tb) microfibers fabricated by electronspinning method by changing the doping ions. Highlights: ► ZnAl{sub 2}O{sub 4}: A{sup 3+} (A = Cr, Eu, Tb) microfibers were obtained by electronspinning method. ► Luminescence properties were due to the transitions of Cr{sup 3+}, Eu{sup 3+} and Tb{sup 3+} ions. ► A new band was observed around 600 nm in CL spectra of ZnAl{sub 2}O{sub 4}: Cr{sup 3+} microfibers. -- Abstract: One-dimensional ZnAl{sub 2}O{sub 4} and ZnAl{sub 2}O{sub 4}: A{sup 3+} (A = Cr, Eu, Tb) microfibers were fabricated by electrospinning method. X-ray diffraction pattern confirmed that the fibers were composed of the cubic ZnAl{sub 2}O{sub 4} phase. Scanning electron microscopy and transmission electron microscopy results indicated that the ZnAl{sub 2}O{sub 4} microfibers annealed at 1000 °C were composed of some smaller nanoparticles and the diameters of the microfibers were in the range of 140–230 nm. Under the excitation of ultraviolet and low-voltage electron beams (3–5 kV), the ZnAl{sub 2}O{sub 4}: A{sup 3+} (A = Cr, Eu, Tb) samples showed the emission of the host and the doping ions. The evolution of the optical propertiesmore » of microfibers with increasing the doping concentration was investigated in detail. Green and red emissions can be realized in ZnAl{sub 2}O{sub 4} microfibers by changing the doping ions. The ZnAl{sub 2}O{sub 4}: A{sup 3+} (A = Cr, Eu, Tb) microfibers have potential applications in full-color field emission displays.« less
