“…Since the establishment of molecular plating by Parker and Falk [1] 60 years ago, knowledge about the method has been gained via many different methods. Via different microscopic methods, like RI, SEM and AFM, and different spectroscopic methods, like alpha and gamma spectroscopy, EDS, XPS, XRD, RBS, IR, and Raman spectroscopy [2,4,7,[13][14][15][16][17]19,27], a more precise understanding of the process of MP and of the chemical composition of the thin films was obtained. It became clear that no nitrates or chlorides are deposited, but that the thin film consisted mainly of oxides and hydroxides.…”

“…[13,15,19,26]. However, these methods are all unable to provide information on the chemical composition of the thin films, which is why spectroscopic methods, like IR, Raman, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), or ion beam spectroscopy like elastic recoil detection analysis (ERDA), Rutherford backscattering (RBS) or proton-induced X-ray emission (PIXE), were also used later [2,13,15,16,19,[27][28][29].…”

“…They proposed the hydroxide ions to act as bridge ligands between the uranyl ions as a possible structure in the thin film. With more analytical investigations, it became clear that the MP process is even more complex than a hydroxide precipitation, and the thin films contain more than only oxide and hydroxide species [2,[14][15][16][17]19,27].…”

“…The usage of a SEM with a spatial resolution of <1 µm [4] made it clear that the molecular plated thin films were not homogeneous and closed surfaces as was inferred from radiographic images, which have a spatial resolution of >100 µm [33], but consisted of many cracks and tiles, referred to as "mudcracking" [1,4,20,26,27]. Pictures of such tiles are visible in Fig.…”

“…It is also unknown why the layer thickness is limited to 800 µg/cm 2 and how this limit can be exceeded [3,4]. Although individual components such as oxides, hydroxides, carbonates, and carboxylates have been identified in the thin films [2,7,[12][13][14][15][16][17]19,27], the ratios of the individual components to each other are still unknown. It is therefore not yet possible to determine a sum formula for the composition of the film.…”

Molecular plating is a well-established and widely used method for producing thin films of various elements, which are used in variety of nuclear physics applications. Sixty years have passed since the method was established, and some insights into the chemical process underlying the method and the composition of the thin films have been gained. A brief overview of what has been learned about molecular plating since its introduction and the methods applied in the characterization of molecular plated thin films is given here. Through various spectroscopic and microscopic methods, the process of molecular plating and the chemical composition are gradually being elucidated, albeit we still do not understand all aspects.

The heaviest elements can exclusively be produced in actinide-target based nuclear fusion reactions with intense heavy-ion beams. Ever more powerful accelerators deliver beams of continuously increasing intensity, which brings targets of current technology to their limits and beyond. We motivate efforts to produce targets with improved properties, which calls for a better understanding of targets produced by molecular plating, the current standard method. Complementary analytical methods will help shedding more light on their chemical and physical changes in the beam. Special emphasis is devoted to the aspect of the optimum target thickness and the choice of the backing material.
