Colloidal aqueous solutions of nanocrystals based on LnVO 4: Eu 3+(Ln= La, Gd, Y, Sm)
with different form factors and sizes from 2 to 300 nm were obtained. The main
characteristics (volume, mass, density, specific surface area) of these disperse systems in
the solid phase were calculated based on transmission electron microscopy data. UV/Vis
spectroscopy was used to show that light absorption depended linearly on the nanoparticle
concentration in solution in the range 5· 10–5—1· 10–3 M (0.01–0.25 g/L). Extinction …
