Fabrication and Characterization of Gd2O3: Yb3+, Er3+ Upconversion Nanofibers
Gd2O3:Yb3+,Er3+上转换纳米纤维的制备与表征

PVA/Gd(NO3)3+Yb(NO3)3+Er(NO3)3] composite nanofibers were fabricated by the combination of sol-gel method and electrospinning.Gd2O3:Yb3+,Er3+ upconversion nanofibers were obtained by the calcination of relevant composite nanofibers.The samples were characterized by using XRD,SEM,TG-DTA,FTIR and fluorescence spectroscopy techniques.The results show that the composite nanofibers are amorphous in structure,and Gd2O3:Yb3+,Er3+ upconversion nanofibers are cubic in structure with space group Ia3.The mean diamete...
