Synthesis of nanosize europium oxide particles by using W/O microemulsion

Europium hydroxide particles with an average diameter of 10 nm and a BET surface area of 127 m2/g have been prepared by controlled precipitation in the polyoxyethylene octylphenol (Triton X‐100) (hexanol)/cyclohexane/water microemulsion system. After calcination in air at 750°C, the obtained europiu...

Zusammenfassung:Europium hydroxide particles with an average diameter of 10 nm and a BET surface area of 127 m2/g have been prepared by controlled precipitation in the polyoxyethylene octylphenol (Triton X‐100) (hexanol)/cyclohexane/water microemulsion system. After calcination in air at 750°C, the obtained europium hydroxide particles were readily converted to the nanosize Eu2O3 particles with an average size of 30 nm and a high BET surface area of 36.5 m2/g.
