Figure 6From: Enhanced band-edge photoluminescence from ZnO-passivated ZnO nanoflowers by atomic layer depositionRoom-temperature PL spectrum of the as-grown and ZnO-passivated ZnO nanoflowers. The room-temperature PL spectrum of the as-grown ZnO nanoflowers and the samples coated by the ZnO thin films with varied thicknesses. The inset shows the PL spectra of the ZnO thin film by ALD on silicon substrate.Back to article page
