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 LaVO 4 :Eu nanostructures. Nanorods and nanosheaves have been selectively obtained by tuning the pH value. In particular, LaVO 4 :Eu nanorods covered by EDTA molecules are soluble in water. In addition, research on photoluminescence has demonstrated that Eu 3+ -doped LaVO 4 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. Graphical abstract
