Disordered Cu2O nanowires (NWs) were prepared by a two-step growth method. Photoluminescence properties of Cu2O NWs have been investigated in detail. The excitonic optical properties from the Cu2O NWs are temperature sensitive. At room temperature, a longitudinal optical (LO) phonon replica and visible light emission from exciton recombination were observed for the first time.
