We demonstrated that mixed lanthanide oxide nanoparticles should be potential dual T 2 MRI-FI agents by using three systems of ultrasmall mixed lanthanide (Dy/Eu, Ho/Eu, and Ho/Tb) oxide nanoparticles. Appreciable r 2 values at 1.5 tesla MR fields and appreciable fluorescence in visible region were observed in all samples.
