SrAl2O4: Eu+2, Dy+3 Nanoliflerin Faz Kararlılığı Üzerine Bor Katkısının Etkisi
Effect of Boron Doping on Phase Stability of SrAl2O4: Eu+2, Dy+3 Nanofibers

Atilla Evcin [1]


Bu çalışmada, katkısız, europyum ve disprosyum katkılı SrAl2O4 ve bor katkılı SrAl2O4: Eu2+, Dy3+ fosfor malzemeleri olmak üzere üç farklı grup hazırlanmıştır. Bor katkısının nanoliflerin faz stabilitesi üzerindeki etkisini görmek için farklı oranlarda bor eklenmiştir. Deneysel çalışmalarda elektroeğirme yönteminde süreç değişkenleri olarak; uygulanan voltajın etkisi, şırınga iğnesi ve toplayıcı plaka arasındaki mesafe incelenmiştir. Fosforesan örneklerinin karakterizasyonu, DSC/TG, XRD ve SEM ile gerçekleştirilmiştir. Sentezlenen tozların XRD analizi sonucunda, yapının katkısız ve Eu-Dy katkılı numunede monoklinik SrAl2O4 formunda olduğu ve ortorombik kristal yapılı Sr4Al14O25 yapısına dönüştüğü gözlemlenmiştir. Nanoliflerin SEM fotograflarını inceleyerek, bor katkısının nanolif  yapı üzerinde önemli bir etkiye sahip olduğunu ve bor miktarındaki artışı, daha düzenli ve daha küçük çaplı nanoliflerin meydana geldiği gözlemlenmiştir. Sonuç olarak, bor katkısının SrAl2O4: Eu, Dy yapısının termal, mineralojik ve morfolojik özellikleri üzerinde önemli bir etkisi olduğu belirlenmiştir.

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.
