Solvothermal Synthesis and Photoluminescence of Rod-Like YVO₄:Dy ³⁺ Nanocrystals

Abstract:

YVO ₄:Dy ³⁺ nanorods were synthesized via a solvothermal route at 150°C. The as-prepared products were investigated using the X-ray powder diffraction, transmission electron microscopy, and photoluminescence spectroscopy. The results showed that the average particle sizes of these nanorods are from 20 to 600 nm. The photoluminescence (PL) measurements showed that these nanorods exhibited improved photoluminescence compared with YVO ₄:Dy ³⁺ irregular nanoparticles. It is found that the appropriate calcinations temperature is helpful to improve the yellow emission.
