Abstract

Monodispersed Nd doped ZnO quantum dots were achieved by a hydrothermal method. Low doping concentration (up to 2.5 at%) of Nd resulted in the relatively large sized quantum dots that show room temperature ferromagnetism while further increasing the doping concentration significantly reduced the size and the quantum dots then became antiferromagnetic. Amorphous Nd₂O₃ was formed during the synthesis of monodispersed quantum dots and it separated ZnO cyrstallites and impedes the crystallites growth.
