Yttria stabilized zirconia (YSZ) single crystals doped with Tm₂O₃, Ho₂O₃, and Yb₂O₃ were prepared by the optical floating zone method in order to investigate the effects of varying the Tm³⁺, Ho³⁺, Yb³⁺ contents on the luminescence properties. All samples were shown by powder X-ray diffractometry (XRD) to be in the cubic phase at room temperature with good crystallinity, and the optical bandwidth of about 4.63 eV indicates their suitability for the development of luminescence products. The blue emission peaks from Tm³⁺ following excitation with a 980 nm (1.33 eV) laser increased with Tm³⁺ content reached a maximum in the crystal with 0.30 mol% Tm₂O₃, and then decreased with higher Tm³⁺ concentrations as a result of quenching caused by electric dipole interactions. The ratio of the integral intensities of the green emission peaks at 2.42 eV (539 nm) and 2.36 eV (552 nm) indicate that the probability of the non-radiative transition from the ⁵F₄ level of Ho³⁺ to the ⁵S₂ level decreases with increasing Tm³⁺ concentration. This research also demonstrates that there was competition between Ho³⁺ and Tm³⁺ for the transfer of energy from excited Yb³⁺, and that there was also direct transfer of energy from Ho³⁺ to Tm³⁺. Thus, in YSZ doped with a combination of rare earth ions, the luminescence properties are determined by a combination of energy transfer processes between the different types of rare earth ions, as well as those for the individual ions, and thus presents an opportunity for fine tuning emissions from such crystals to produce a new generation of materials with intense luminescence properties.

氧化钇稳定的氧化锆（YSZ）单晶掺杂的Tm ₂ ö ₃，何₂ ö ₃和Yb ₂ ö ₃为了研究不同的T m的影响由光浮区方法制备³⁺，何³⁺， Yb ³⁺含量对发光特性的影响。所有样品的粉末X射线衍射（XRD）表明，室温下均呈立方相，结晶度良好，约4.63 eV的光学带宽表明它们适合开发发光产品。Tm ³⁺的蓝色发射峰在用 980 nm (1.33 eV) 激光激发后，随着 Tm ³⁺含量的增加，在晶体中达到最大值，0.30 mol% Tm ₂ O ₃，然后随着 Tm ³⁺浓度升高而降低，这是由于电偶极子引起的猝灭相互作用。2.42 eV (539 nm) 和 2.36 eV (552 nm) 处绿色发射峰的积分强度比表明从Ho ³⁺的⁵ F ₄能级到⁵ S ₂的非辐射跃迁概率水平随着 Tm ³⁺浓度的增加而降低。这项研究还表明，Ho 之间存在竞争。³⁺和Tm ³⁺用于从激发态Yb ³⁺的能量转移，并且还有能量从Ho ³⁺直接转移到Tm ³⁺。因此，在掺杂稀土离子组合的 YSZ 中，发光特性是由不同类型稀土离子之间以及单个离子的能量转移过程的组合决定的，因此提供了一个机会。调整这些晶体的发射以生产具有强烈发光特性的新一代材料。
