From: Extended photoresponse and multi-band luminescence of ZnO/ZnSe core/shell nanorods
Raman spectra of samples A (a), B (b), C (c), and D (d), recorded by exciting the samples with 325-nm laser beam. The inset shows the Raman bands of ZnO/ZnSe core/shell NRs (samples B, C, and D in the downward order).
