Figure 5: EPR spectroscopy measurements.
From: A nanocomposite superstructure of metal oxides with effective charge transfer interfaces
EPR spectra of (a) ZnO mesocrystals, (b) CuO mesocrystals, (c) ZnO-CuO mesocrystals and (d) ZnO-CuO nanocrystals at 77 K in vacuum (black lines are acquired in dark and red lines are under ultraviolet irradiation; sim. and obs. are the simulated and observed spectra, respectively). To reproduce the observed spectrum for ZnO, simulations were performed with the following EPR parameters: g=1.960, g=2.005 (gxx=2.0077, gyy=2.0010, gzz=2.0059) and g=2.019 (gxx=2.0185, gyy=2.0188, gzz=2.0044)34,35.
