Findings
InAs layer exhibits multipeak PL spectra.
PL decay is nonexponential and energy-dependent.
Decay rates are very slow.
Abstract
Time- and spectrally-resolved PL from a periodic array of InP/InAs/InP core-multishell nanowires is presented. InAs layer shows multipeak PL spectra. PL decay is nonexponential and very slow, with decay rate depending on energy.
