beta-SiAlON:Eu2+ phosphors synthesis usually requires higher temperatures and higher nitrogen pressure conditions. In the present research, a low temperature technique has been developed to synthesize both beta-SiAlON and Eu-doped beta-SiAlON fibers by electrospinning combined with carbothermal reduction nitridation (CRN). The carbon sources used as reductant in CRN procedure have been optimized to effectively produce a well-crystallized beta-SiAlON phase at lower temperatures of 1370-1500 degrees C. Additionally, through adding sucrose and covering activated carbon powders on the top of fiber precursor layers, the highly-pure beta-SiAlON and beta-SiAlON:Eu2+ fibers could be obtained. The pyrolysis behavior of fiber precursors, crystalline phase, morphology, and UV excited luminescence properties of the produced ceramic fibers were also studied by using TG-DSC measurement, XRD analysis, SEM observation, and spectrometer method. The resultant fibers exhibit a smooth surface and an uniforme morphology with a substantial length. Moreover, the beta-SiAlON:Eu2+ fibers thus prepared show a blue light emission peaked at 470 nm under UV excitation. (C) 2015 Elsevier B.V. All rights reserved.
