摘要

金属氧化物纳米晶体，如ZrO2和HfO2，作为光学活性镧系离子的宿主。然而，合成具有复杂结构的胶体稳定纳米晶体仍然具有挑战性。我们率先合成了金属氧化物核/壳纳米晶体，其中HfO2外延生长在ZrO2上。通过在ZrO2:Eu和ZrO2:Eu/ZrO2表面生长氧化锆保护壳后的光致发光研究，证明了壳层对光学性能的有利影响。

Metal Oxides of Group 4: General Insights and the Synthesis of ZrO₂/HfO₂ and ZrO₂:Eu/ZrO₂ Core/Shell Nanocrystals.

Metal oxide nanocrystals, like ZrO2 and HfO2, serve as hosts for optically active lanthanide ions. However, synthesizing colloidally stable nanocrystals with complex architectures remains challenging. We have pioneered the synthesis of metal oxide core/shell nanocrystals, where HfO2 epitaxially grows onto ZrO2. The beneficial effect of the shell on the optical properties is demonstrated by investigating the photoluminescence of ZrO2:Eu and of ZrO2:Eu/ZrO2 after growing a protective zirconia shell on it.[1].
