The dependence of temperature synthesis of GdVO4:Eu3+ nanoparticle phosphors by solvothermal method

Eu3+ doped GdVO4:Eu3+ nanopowders have been synthesized using a solvothermal method. The crystallinity, grain size and photoluminescence (PL) of the nanopowders are highly dependent on the different sintering temperature. The relationship between the crystalline and morphological structures and the luminescent properties was studied. Sintering temperature was found to effectively enhance not only the morphology but also the luminescent brightness of GdVO4:Eu3+ nanopowders. Photoluminescence measurements of the GdVO4:Eu3+ powders show red emission at the 612 nm (5D0–7F2) wavelength. The PL intensity, grain size and particle size exhibit a similar behavior as a function of the sintering temperature.
