Raman and photoluminescence spectroscopy investigations of ZnO nanostructures

Figures & data

Figure 1. 488 nm excitations on the ZnO nanostructures in various forms.

Figure 2. Photoluminescence of ZnO in the solid, thin film and nanowire forms.

Figure 3. Raman spectra of ZnO powder excited with different laser wavelengths. The multiphonon ZnO nanowire resonant spectra are used for comparison.

Figure 4. UV Raman and photoluminescence spectra of ZnO nanowires excited at 244 nm (red) and 325 nm (blue) respectively, showing the multiphonon vibration modes. The inset is the photoluminescence spectra.
