Structural, electronic, and Raman scattering properties of strontium oxide nanoclusters are assessed through density functional theory. Binding energy and second‐order energy calculations clearly show the role played by the geometry on the relative stability of the (SrO)n clusters, revealing that by deviating from cuboid shape these systems tend to become less stable and therefore more reactive, leading to a higher electron affinity and lower ionization potential. Size and shape effects observed in Raman scattering indicate that it might be feasible to discriminate between one and two‐dimensional grown clusters. Additionally, signatures of clusters possessing rings in the structure are also identified in Raman spectra. The results thus suggest that Raman spectroscopy could be an interesting alternative experimental technique to better characterize small nanoclusters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
