This letter presents optical spectra of EL?+ in nanocrystalline Eu,O, and Eu3+: Y203. The nanocrystalline particles condense in the monoclinic crystal structure after CO,-laser vaporization of metal oxide ceramics. The spectra of 14 nm Eu,O, particles have the same sharp lines as do micrometer-size
