Schematic representation of hybrid films in the polymer template showing the dispersion of CdSe quantum dots in P4VP block and Au nanoparticles in PS block, indicated by the red and brown dots, respectively.
Representative energy distribution inside the film (energy decreasing from red to blue) due to the plane wave excitation at 488 nm wavelength incident along the normal Z-axis; shown using a Z-section of a 9 cell volume. The Au nanoparticles appear in red primarily, the quantum dots in the inner cylinder appear in yellow or green, and the PS/P4VP matrices are minimally polarized.
