摘要

在乙二胺四乙酸（EDTA）的存在下，为了控制 LaVO4:Eu 纳米结构的锆石型四方相的尺寸和形态，我们构思了一种直接的水热法。通过调节 pH 值，可以选择性地获得纳米棒和纳米波。特别是被 EDTA 分子覆盖的 LaVO4:Eu 纳米棒可溶于水。此外，光致发光研究表明，掺杂 Eu3+ 的 LaVO4 纳米棒在紫外线照射下会发出明显的红色光。这种现象有望用于视觉显示、催化和生物成像等多个领域。

Hydrothermal synthesis and photoluminescence of single-crystalline LaVO4:Eu3+ nanorods/nanosheaves

In the presence of ethylenediaminetetraacetic acid (EDTA), a straightforward hydrothermal method was conceptualized for the purpose of controlling the size and form of the zircon-type tetragonal phase of LaVO₄:Eu nanostructures. Nanorods and nanosheaves have been selectively obtained by tuning the pH value. In particular, LaVO₄:Eu nanorods covered by EDTA molecules are soluble in water. In addition, research on photoluminescence has demonstrated that Eu³⁺-doped LaVO₄ nanorods exhibit significant red emission when exposed to ultraviolet light. This phenomenon has the potential to be utilized in a variety of disciplines, including visual display, catalysis, and biological imaging.
