Luminescence enhancement of Y2O3:Er3+ and Y2O3:Yb3+/Er3+ sub-microcrystals by Zr4+ ions Co-doping
The co-doping effect of Zr4+ ions on upconversion (UC) luminescent properties in visible region of Y2O3: Er3+ and Y2O3: Er3+, Yb3+ sub-microcrystals prepared by urea precipitation method has been investigated under 980 nm excitation. Compared with the original Y2O3: Er3+ and Y2O3: Er3+, Yb3+ sub-mic...

| description | The co-doping effect of Zr4+ ions on upconversion (UC) luminescent properties in visible region of Y2O3: Er3+ and Y2O3: Er3+, Yb3+ sub-microcrystals prepared by urea precipitation method has been investigated under 980 nm excitation. Compared with the original Y2O3: Er3+ and Y2O3: Er3+, Yb3+ sub-microcrystals, the UC luminescence of sub-microcrystals with similar size was enhanced after Zr4+ ions co-doping. The UC luminescent properties have been discussed in detail via luminescence spectra, decay curve analysis and a suitable energy level diagram. The enhancement mechanism of UC luminescence in the two series of Zr4+ ions doped sub-microcrystals was attributed to the complex crystal field around Er3+ ions caused by Zr4+ ions co-doping. After Zr4+ ions substituted Y3+ions and entered the crystal lattice, the charge mismatch and lattice distortion made the crystal field more complex. This research contributes to the understanding of UC luminescent properties of lanthanide (Ln3+) ions doped UC materials and their technological applications in fields such as bioimaging, drug delivery, and optical temperature sensors. |
