电纺丝方法制备GaN∶Eu2+纳米纤维与发光特性
Preparation and characterization of Eu2+-doped GaN luminescent nanofibers by electrospinning method
摘要
Abstract
Eu2+-doped GaN (GaN∶Eu2+) nanofibers were synthesized by a facile approach that combined electrospinning and ammonification techniques.SEM and TEM images revealed that the nanofibers consist of GaN nanoparticles with uniform size.XRD result showed that the GaN∶Eu2+ sample predominantly exhibited the hexagonal phase of GaN (h-GaN) and the average grain size was evaluated to be 7.3 nm.Further Raman characterization showed that two extra GaN Raman shifts with the peaks of 252 and 422 cm-1 were observed.As was expected,characteristic strong blue emission from Eu2+ ions doped in GaN matrix was observed at 407 nm in the photoluminescence spectrum.关键词
