Micro-Raman spectroscopy coupled with scanning electron microscopy has been used for the first time to analyze micrometer-size particles of various uranium oxides [UO2, U3O8, UO3,and UO4 · 4(H2O)] deposited on carbon disks. Despite a loss of signal-to-noise ratio of an order of magnitude with regard to the stand-alone micro-Raman spectroscopy, all uranium oxides are successfully identified in particles by in-scanning electron microscopy Raman analysis. Moreover, particles as small as 1 µm can be analyzed.
