Ytterbia and erbia dual-doped zirconia(ZrO_2:Yb~(3+),Er~(3+))nanophosphors were successfully synthesized by high-temperature fuel combustion at 1000°C for 2 h.The effects of dopant concentration on the structure and upconversion properties were investigated by X-ray diffraction,transmission electron microscopy and photoluminescence,respectively.XRD patterns indicate that the main phase of products belongs to cubic ZrO_2 fluorite-type structure.TEM results show that different fuels have great influence on the morphologies of dual-doped ZrO_2 samples.Under 980 nm excitation,the glycine-calcined nanophosphors show high stimulated luminescence and doped-ion concentration-depended intensities.The intensely red upconversion emissions are attributed to the fact that the dual-doped Yb~(3+)and Er~(3+)ions result in the non-radiative relaxation,energy migration,and cross relaxation.
Ytterbia and erbia dual-doped zirconia (ZrO_2: Yb ~ (3 +), Er ~ (3 +)) nanophosphors were successfully synthesized by high-temperature fuel combustion at 1000 ° C for 2 h. The effects of dopant concentration on the structure and upconversion properties were investigated by X-ray diffraction, transmission electron microscopy and photoluminescence, respectively. XRD patterns indicate that the main phase of products belongs to cubic ZrO 2 fluorite-type structure. TEM results show that different fuels have great influence on the morphologies of dual-doped ZrO 2 samples. 980 nm excitation, the glycine-calcined nanophosphors show high stimulated luminescence and doped-doped concentration-depended intensities. The intensely red upconversion emissions are attributed to the fact that the dual-doped Yb ~ (3+ and Er ~ (3+) ions result in the non-radiative relaxation, energy migration, and cross relaxation.
