Time- and Spectrally-Resolved PL Study of a Regular Array of InP/InAs/InP Core-multishell Nanowires

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.
