Synthesis and Properties of Hollow CaSi2O2N2:Eu2+ Luminescence Fibers

doi:10.15541/jim20130639

Abstract

Abstract:

Hollow Eu²⁺ doped CaSi₂O₂N₂ and Ca-Si-O-Eu nanofibers were prepared through electrospinning combined with gas-reduction-nitridation method. The Ca-Si-O-Eu precursor was smooth and uniform, has a length arrange from ten to hundred micrometers. The as-obtained sample not only keeps the hollow structure but also assembles to a film. XRD patterns reveal that the sample nitrided under 1300℃ for 5 h are crystallized well and maintained CaSi₂O₂N₂ phase after Eu²⁺ doping. The emission spectra of Eu²⁺ doped CaSi₂O₂N₂ under the 400 nm ultraviolet light irradiation has a board peak centered at 550 nm, which results from Eu²⁺ 5d-4f transition. In comparison with CaSi₂O₂N₂:Eu phosphor powders and fiber film, the hollow CaSi₂O₂N₂:Eu phosphor fiber film has stronger emission intensity under PL measurement.

Key words: hollow fiber, electrospinning, luminescence fiber, oxynitride
