柔性Eu3+掺杂SiO2纳米纤维薄膜的制备及其发光性能
Preparation and Luminescence Properties of Flexible Eu3+ Doped SiO2 Fibrous Membranes
摘要
Abstract
Eu3+ doped SiO2 fibrous membranes were prepared by Sol-Gel and electrospinning methods. The obtained samples were chacterized by SEM, XRD, FT-IR, TG, PL,etc. By heat-treatment, the organic components were re-moved slowly and the diameters of the Eu3+ doped SiO2 fibers decreased. SEM images exhibit that the surface of the fibers retains smooth and uniform after heat-treatment. By controlling the heating rate, the Eu3+ doped SiO2 fibrous membranes present relatively high tensile strength at about 4.31 MPa after heat-treatment at 750℃. The samples ex-hibit no cracks after bending and recovering process. By excited by 392.6 nm light, the emission peaks between 570-670 nm are observed, which attributes to the5D0→7FJtransition. The strongest emission peak situates at 616 nm results from Eu3+5D0→7F2 transition. The optimal heat-treatment temperature is 750℃. PL spectra also show that the luminescence intensity attains the highest value at the concentration of 8mol% Eu3+doped.关键词
