Low-temperature photoluminescence imaging and time-resolved spectroscopy of single CdS nanowires

Year: 2006

Type: article

Abstract: Time-resolved photoluminescence (PL) and micro-PL imaging were used to study single CdS nanowires at 10K. The low-temperature PL of all CdS nanowires exhibits spectral features near energies associated with free and bound exciton transitions, with the transition energies and emission intensities varying along the length of the nanowire. In addition, several nanowires show spatially localized PL at lower energies which are associated with morphological irregularities in the nanowires. Time-resolved PL measurements indicate that exciton recombination in all CdS nanowires is dominated by nonradiative recombination at the surface of the nanowires.
