Figure 6From: The effect of dopant and optical micro-cavity on the photoluminescence of Mn-doped ZnSe nanobeltsCharacterization of another ZnSe Mn ( CH 3 COO ) 2 nanobelt with low Mn2+concentration (0.39%). (a) SEM image and EDS. (b) Dark-field emission image. The inset is the corresponding bright-field optical image. (c) The corresponding PL spectrum. (d) The corresponding PL mapping images of individual emission sub-bands. The scale is 10 μm.Back to article page
