Abstract
This letter presents optical spectra of Eu 3+ in nanocrystalline Eu 2O 3 and Eu 3+:Y 2O 3. The nanocrystalline particles condense in the monoclinic crystal structure after CO 2-laser vaporization of metal oxide ceramics. The spectra of 14 nm Eu 2O 3 particles have the same sharp lines as do micrometer-size particles, and the spectra of 5 nm Eu 2O 3 particles show the sharp lines superimposed on broad and shifted bands. The spectra of 12 nm particles prepared from Eu 0.2Y 1.8O 3 starting material show two phases that are attributed to slightly disordered Eu 2O 3 and crystalline Eu 3+:Y 2O 3. The spectra of 5 nm particles prepared from Eu 0.2Y 1.8O 3 show broad bands similar to the 5 nm Eu 2O 3 spectra.
