Smart nanostructured materials involve an extensive understanding of their morphology and chemical composition to develop novel designs. Optical and transport properties could be strongly dependent on the morphology of such nanomaterial. Additionally, one can broadly increase the capabilities of such nanostructure by mixing several chemical elements or compounds. Spectroscopy techniques such as Raman, Photoluminescence and SEM-CL, play a key role for a comprehensive characterization of such complex and novel nanomaterial. However, a critical point on this type of study is the ability to measure a specific area or artefact at the same location through all the techniques available. Being colocalized, allows a comprehensive characterization of the sample and a precise superimposition of the images. HORIBA Scientific developed a new relocalization solution, called nanoGPS navYX™.

Multimodal spectroscopy techniques for nanostructured materials characterization

In this article, we present the combination of Raman spectroscopy, Photoluminescence and SEM-CL techniques, where the instruments weren’t physically connected. Smart nanostructured materials require a comprehensive understanding of their morphology, elemental and chemical composition. nanoGPS Suite solution allows a colocalized combination of a variety of microscopy techniques, providing a full characterization of nanostructured materials and a precise superimposition of the results obtained.
