Rare earth orthovanadates are of extensively interest as various applications. Most of previous approaches need harsh reaction conditions. So, it has an important meaning to develop the general synthetic process for rare earth orthovanadate nanocrystals under mild and ambient reaction conditions. In this presentation, I reported a general synthetic process of uniform rare earth orthovanadate (LnVO4, Ln = Y and lanthanides) nanocrystals with various shapes. LnVO4 nanocrystals were prepared via the mild reaction of Ln(III) acetate, oleylamine, oleic acid in xylene and vanadyl sulfate in water. And I also demonstrated their electrochemical performance. I applied LnVO4 nanocrystals to cathode material using feature of nanocrystal, very large surface per weight. In addition, mesoporous silica-coated Eu3+ doped GdVO4 nanocrystals exhibit strong red photoluminescence and the Gd3+ in GdVO4 can be used as a T1 contrast agent for MRI. |
