Abstract
In this study, three varied groups as pristine, europium and dysprosium doped SrAl2O4 and boron doped SrAl2O4:Eu2+, Dy3+ phosphorus materials were prepared. To see the effect of boron additive on phase stability of nanofibers, different ratios of boron were added. In the experimental studies, as process variables during the electrospinning method; the effect of the applied voltage, the distance between the syringe needle and collector plate were examined. The characterization of phosphorescence samples was carried out with DSC/TG, XRD and SEM. As a result of XRD analysis of the synthesized powders the structure was observed to be in monoclinic SrAl2O4 form in the pristine and Eu-Dy doped samples and turn into orthorhombic crystal-structured Sr4Al14O25 structure. Through examining the SEM photos of nanofibers, its observed that boron additive has a significant effect on nanofiber structure and with the increase in the boron amount, much order and much small-diameter nanofibers occur. Consequently, it is determined that boron additive has a significant effect on thermal, mineralogical and morphological properties of SrAl2O4: Eu, Dy structure.
