“…There are additional possibilities for more complex NP architectures, finalized to the realization of core@shell, dumb-bell geometries, nanoalloys etc [47][48][49][50]. Also, chemisorption of functional molecules on in-flight NPs or growth of NPs in solid matrix and/or multilayered NP films are possible, with some implementations of the equipment.…”

“…A recent instrumental development of LPGAS is the planar multimagnetron source, with three targets mounted on the same assembly [50]. Nanoalloy particles and dumb-bell NPs can then be realized in a one-step procedure inside the source, with great flexibility in varying the relative alloy composition and size.…”

The experimental activity on core@shell, metal@oxide and oxide nanoparticles (NP) grown with physical synthesis, and more specifically by low pressure gas aggregation sources (LPGAS) is reviewed, through a selection of examples encompassing some potential application in nanotechnology. After an introduction on applications of NP, a brief description of the main characteristics of the growth process of clusters and NP in the LPGAS is given. Successively, some relevant case studies are reported: • Formation of native oxide shells around the metal cores in core@shell NP. • Experimental efforts to obtain magnetic stabilization in magnetic core@shell NP by controlling their structure and morphology. • Recent advancements in NP source design and new techniques of co-deposition, with relevant results in realization of NP with greater variety of functionalities. • Recent results on reducible oxides NP, with potentialities in nano-catalysis, energy storage and other applications. Although this list is far from being exhaustive, aim of the authors is to give the reader in a descriptive way some glimpse of the physics behind the growth and the studies of low pressure gasphase synthesized NP, with their ever-growing potentialities for a rational design of new functional materials.

The use of multicomponent targets allows the gas‐phase synthesis of a large variety of alloy nanoparticles (NPs) via gas aggregation sources. However, the redeposition of sputtered material impacts the composition of alloy NPs, as demonstrated here for the case of AgAu alloy NPs. To enable NPs with tailored Au fractions, in operando control over the composition of the NPs is in high demand. We suggest the use of optical emission spectroscopy as a versatile diagnostic tool to determine and control the composition of the NPs. A strong correlation between operating pressure, intensity ratio of Ag and Au emission lines, and the obtained NP compositions is observed. This allows precise in operando control of alloy NP composition obtained from multicomponent targets.
