Figure 8.

(A) SEM images of a crystalline lattice assembled from a-Se@Ag2Se core-shell colloidal spheres. (B) SEM image of the same crystal after it had been annealed at 150 °C for 10 min. (C) Reflectance spectra recorded from an a-Se@Ag2Se crystal. The temperature was increased from room temperature (R.T.) to 110 and 150 °C, respectively, and then reduced to 110 °C.
