Figure 4From: Synthesis and optical property of one-dimensional spinel ZnMn2O4 nanorods UV-Vis spectra and plots for band gaps determination. (a) The UV-Vis diffuse reflectance spectra of the ZnMn2O4 nanorods calcined at 500, 650, and 800°C, respectively; (b) plots of (αhυ)2 versus photon energy of ZnMn2O4 nanorods calcined at 500, 650, and 800°C, respectively.Back to article page
