(Ga1-xZnx)(N1-xOx) is a visible absorber of interest for solar fuel generation. We present a first report of soluble (Ga1-xZnx)(N1-xOx) nanocrystals (NCs) and their excited-state dynamics over the time window of 10(-13)-10(-4) s. Using transient absorption spectroscopy, we find that excited-state decay in (Ga0.27Zn0.73)(N0.27O0.73) NCs has both a short (<100 ps) and a long-lived component, with a long overall average lifetime of similar to 30 mu s. We also find that the strength of the visible absorption is comparable to that of direct band gap semiconductors such as GaAs. We discuss how these results may relate to the origin of visible absorption in (Ga1-xZnx)(N1-xOx) and its use in solar fuel generation.
