Lanthanide isotopes such as Pm-147, Gd-153, Tb-161, and Lu-177 are indispensable for nuclear medicine and materials research. Their domestic supply, however, is constrained by one of the toughest challenges: separating neighboring lanthanides whose chemical properties are nearly identical.

Molecular plating (MP) is a widely used technique for preparing thin targets for nuclear physics applications, including cross-section measurements [1-3] and muon spectroscopy [4]. Target characterization typically relies on areal density (mg/cm²), which gives the total amount of material but not its spatial distribution. In non-uniform films, the same total mass can correspond to different...
