摘要：Eu3+- or Tb3+-doped MgAl2O4 hollow spheres have been successfully synthesized via facile hydrothermal method by using carbon spheres as template followed by a subsequent heat treatment. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results showed that the hollow microspheres possessed diameters in the range of 1 similar to 2.5 mu m and shell thickness of 60 similar to 80 nm. A possible formation mechanism for hollow spheres was proposed. MgAl2O4:Eu3+ show strong red emission at 619 nm corresponding to the forced electric dipole D-5(0)-> F-7(2) transition of Eu3+, and MgAl2O4:Tb3+ exhibit strong green emission at 545 nm corresponding to D-5(4)-> F-7(5) transition of Tb3+.
