Sol-gel synthesis and luminescent properties of YVO4 : Eu nanoparticles

Experimental results on the synthesis of luminescent YVO4: Eu nanoparticles with the method of metalopolymer gel decomposition are presented. The sizes of the coherent scattering regions according to the X-ray diffraction data range from 25 to 40 nm and increase with the increase of the annealing temperature from 800 to 1000A degrees C. It was shown that the obtained nanoparticles demonstrate good luminescent properties. The luminescence intensity and lifetime of the excited state increase with the increase of the annealing temperature. Nanoparticles are good candidates to use as luminescent labels.
