A new approach that uses mixed supercritical solvents of water/1-propanol and water/methanol (400 °C, 40 MPa) to prepare morphology-controlled precursor materials in a very short reaction time, such as 10 min, followed by calcinations has been developed to form Eu3+:Y2O 3 microspheres of 2-3 μm in diameter or microcubes of 2-3 μm in side length, respectively. Eu3+:Y2O3 microspheres and microcubes exhibited strong red emission at 610 nm corresponding to 5D07F2 transition. The highest photoluminescence emission was obtained for the microspheres after calcination at 1000 °C for 1 h in air.
