Throw some shapes: Differently shaped hematite nanostructures, that is, nanocubes, nanorhomohedra, nanorice, and spheroidal nanoparticles. Initial transient absorption spectra for the four samples vary widely. Single-value decomposition global fitting is used to deconvolute the initial spectra into B-spectra. For all samples, the fast components have broader B-spectra than the slow components, indicating that the fast components of the decay involve multiple electronic transitions, or states that have broad electronic absorption spectra.
