From: Correlative Study of Enhanced Excitonic Emission in ZnO Coated with Al Nanoparticles using Electron and Laser Excitation

Figure 5

(a) Bottom: PL (blue) and CL (red) spectra at 5 kV of the uncoated (solid lines) and Al-coated (dashed lines) ZnO at 10 K. Top: Corresponding PL and CL enhancement factor as a function of energy. Dotted green lines illustrate the DBX-related transitions in ZnO, while the dashed olive lines represent the FX-related emissions. (b) PL and 5 kV CL spectra and enhancement factors at a temperature of 80 K.
