Abstract
The present invention relates to Eu (II) compound nanocrystals doped with transition metal ions. Such a constitution generates quantum size effects of an Eu (II) compound nanoparticle, while the transition metal ions can affect a magnetooptical property of the Eu (II) compound nanoparticle. Thus, the magnetooptical property can be improved.
