| 英文摘要 | Samples of E3+/Yb3+ co-doped ZrO2-Al2O3 powders were prepared by solid-state reaction. The upconversion luminescence spectrum excited by 980 run laser light suggests that there exit three main emission bands: one red emission band centered at 654 mn and two green emission bands centered at 545 and 525nm, corresponding to E3+ ions transitions of F-4(9/2) -> I-4(15/2), S-4(3/2) -> I-4(15/2) and H-2(11/2) -> I-4(15/2), respectively. The emission band centered at 654 nm is much stronger than the other two. The upconversion mechanisms are discussed and it is bound that both red emission and green emissions are two-photon processes. It can be seen from the XRD spectra that zirconia (ZrO2) mainly. exists as a cubic phase, while Al3+ is implanted into the ZrO2 lattice, producing the ZrO1.87. The solid solution towers the site symmetry of the lattices in ZrO2 crystals, which promotes the upconversion efficiency. |
