The luminescent properties of europium-doped tin dioxide nanocrystallites

摘要

The europium-doped tin dioxide nanopowders were synthesized using modified Pechini method. The samples with different Eu~(3+) concentration were sintered at different temperatures. In order to determination of structure and morphology of obtained powders X-ray diffraction (XRD) measurement and transmission electron microscopy (TEM) investigation were carried out. Photoluminescence of obtained powders were measured. Intensity of emission was compared using (blue ZnS:Ag) reference peak method. After that mixed powders were deposited on ITO-glass slide. The cathodoluminescence of obtained layers was also measured and compared. The properties and the potential application of obtained nanopowders will be discussed.
