Figure 2From: Novel lanthanide-labeled metal oxide nanoparticles improve the measurement of in vivo clearance and translocation Powder x-ray diffraction spectra for Eu:Gd 2 O 3 flame synthesized nanoparticles. Diamonds correspond to major peaks for monoclinic gadolinium oxide (PDF 00-042-1465) and inverted triangles correspond to monoclinic europium oxide (PDF 00-034-0072).Back to article page
