Paper Abstract

Nanometer-sized YPO4:Eu and YVO4:Eu particles were prepared from alkaline alcohol-water mixture with Y(NO3)3 6H2O, EuCl3 and H3PO4 (or NH4VO4) under reflux. The resultant particles were well crystallized ranging 10-50 nm in diameter by changing reaction conditions. Europium ions in YPO4:Eu and YVO4:Eu was successfully reduced to Eu2+ ions by sodium borohydride under reflux. The peak position of blue emission due to Eu2+ ions (4f-5d transition) in nanocrystals was different among the materials (Y2O3, YVO4 and YPO4).
