Synthesis, structure and spectroscopic assessment of luminescent GdVO4:Dy3+ and DyVO4 nanoparticles

In this paper, we focused on the size effects of GdVO4:2mol% Dy3+ and DyVO4 particles on their structural and optical properties. Highly crystalline particles of different sizes and morphologies with tetragonal zircon-type phase were successfully synthesized by using different techniques of synthesis, such as reverse micelles, co-precipitation and hightemperature solid-state methods. The prepared samples exhibited a number of similarity and diversity in structural and optical properties with a decreasing in particle diameter.
