报道了通过控制组分和晶化过程成功制备（Er 3+，Yb 3+）共掺杂ZnO透明杂化材料。单沉淀的ZnO纳米晶在玻璃表面上沿c轴方向沿着择优取向，在ZnO的带隙能处产生强烈的发光。Er3+和Yb3+离子在低声子能量的ZnO纳米晶体周围聚集，在可见光区实现了增强的双光子上转换发射。此外，玻璃陶瓷表现出典型的顺磁性与反铁磁相互作用。这种低成本、易成型和环境友好的块状材料中的多功能组合可以找到广泛的器件应用。
We report the successful fabrication of (Er3+, Yb3+)-co-doped ZnO transparent hybrid materials by controlling compositions and crystallization. The singly precipitated ZnO nanocrystals were preferentially oriented along the c-axis on the glass surface, leading to an intense luminescence at the bandgap energy of ZnO. The Er3+ and Yb3+ ions assembled around the low-phonon-energy ZnO nanocrystals, achieving an enhanced two-photon upconversion emission in the visible region. In addition, the glass ceramic exhibited typical paramagnetism with antiferromagnetic interactions. The multifunctional combination in such a low-cost, easily shapable and environmentally friendly bulk material may find a wide range of device applications.
