Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="pssa201329139-sec-0001" sec-type="section"> <p>LuBO₃:Ln³⁺ (Ln = Eu, Tb) nanofibers were synthesized via electrospinning combined with heat treatment. The structure analyses show that the as‐prepared LuBO₃:Ln³⁺ (Ln = Eu, Tb) nanofibers have porous morphology and average diameters of 200–300 nm, which consist of closely lined nanoparticles with the size of about 30 nm. The fluorescence spectra show that the <italic>R</italic>/<italic>O</italic> values are 1.02 and 1.12 for LuBO₃:3 mol% Eu³⁺ nanofibers sintered at 800 and 900 °C, respectively. For LuBO₃:<italic>x</italic>Tb³⁺ (<italic>x</italic> = 1, 3, and 5 mol%) nanofibers, the emission intensities and the fluorescence lifetime increase slightly with increasing Tb³⁺ concentration. The fluorescence characteristic of LuBO₃:Ln³⁺ (Ln = Eu, Tb) nanofibers is discussed.</p> </sec> </abstract>
