Zn₂GeO₄ is considered a very promising alternative to current luminescent semiconductors. Previous results suggest that its emitted wavelength may depend on different variables, such as particle size and morphology, among others. In this work, we have prepared pure and highly homogeneous Zn₂GeO₄ nanorods under hydrothermal synthesis conditions with a willemite-like structure. Their luminescent properties have been explored and their band gap is estimated, which are distinct from those of previously reported Zn₂GeO₄ bulk particles. Therefore, our results identify particle morphology as a crucial factor for maximizing and fine-tuning the luminescence of Zn₂GeO₄ nano-phosphors.

Zn2GeO4 纳米磷光体的可控合成和形貌依赖性发光效率

Zn ₂ GeO ₄被认为是当前发光半导体的非常有前途的替代品。先前的结果表明，其发射波长可能取决于不同的变量，例如颗粒尺寸和形态等。在这项工作中，我们在水热合成条件下制备了纯且高度均匀的具有类硅锌矿结构的Zn ₂ GeO _{4纳米棒。已经探索了它们的发光特性并估计了它们的带隙，这与之前报道的 Zn 2} GeO ₄块体颗粒不同。因此，我们的结果表明颗粒形态是最大化和微调 Zn ₂ GeO ₄纳米磷光体发光的关键因素。
