Optical and electrical properties of Mg~(2+)and Li~+ doped Eu~(3+):SnO_2 nanocrystallites

摘要

The europium-doped tin dioxide nanopowders co-doped with Mg~(2+) and Li~+ ions were synthesized using modified Pechini method. In order to determination of structure and morphology of obtained powders the X-ray diffraction (XRD) measurement were carried out. The photoluminescence of obtained powders were measured. Intensity of emission was compared using blue ZnS:Ag reference peak method. The intensity of emission of samples with different Mg~(2+), Li~+ concentration and pure Eu~(3+):SnO_2 were compared. After that mixed powders were deposited on ITO-glass slide. The cathodoluminescence of obtained layers were also measured and compared. In the same time, slurries with obtained nanoparticles were carried out. The layers consisted obtained nanopowders were fabricated from prepared slurries using spin-coating method. The electrical properties of obtained layers measured and compared. The influence of co-doping, properties and the potential application of obtained nanopowders will be discussed.
