Temperature sensitive optical properties of exciton and room-temperature visible light emission from disordered Cu 2 O nanowires
Disordered Cu 2 O nanowires (NWs) were prepared by a two-step growth method. Photoluminescence properties of Cu 2 O NWs have been investigated in detail. The excitonic optical properties from the Cu 2 O NWs are temperature sensitive. At room temperature, a longitudinal optical (LO) phonon replica an...

O nanowires (NWs) were prepared by a two-step growth method. Photoluminescence properties of Cu
2
O NWs have been investigated in detail. The excitonic optical properties from the Cu
2
O 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. |
