Highly luminescent self-organized sub-2-nm EuOF nanowires

Monodisperse sub-2-nm EuOF nanowires are obtained by manipulating the fluorophilicity between crystalline seeds and capping surfactant molecules during the thermolysis of Eu[(C[F.sub.3]COO).sub.3] in oleic acid (OA) and oleylamine (OM). The uniform EuOF nanowires have self-organized on substrates to form parallel aligned superstructures and have exhibited strong [Eu.sup.3+] red emissions with high quantum yields of 65% under the ultraviolet light excitations.
