A facile route to synthesize luminescent YVO4:Eu3+ porous nanoplates

Abstract Porous nanoplates made of yttrium orthovanadate doped with europeum (YVO 4 :Eu 3+ ) have been successfully synthesized via a chemical co-precipitation method using NH 4 VO 3 , Y 2 O 3 , Eu 2 O 3 and ethylene glycol. To investigate the effect of temperature on the pore size and morphology of the final product, the as-synthesized YVO 4 :Eu 3+ nanoplates were subjected to heat treatment at 300 and 600 °C for 2 h. The obtained samples were characterized by X-ray diffractometion, Fourier-transform infrared spectroscopy, transmission electron microscopy, high-resolution transmission electron microscopy and photoluminescence spectroscopy. The experimental results showed that the luminescent properties were significantly enhanced with increasing pore size of the YVO 4 :Eu 3+ porous nanoplates.
