YSZ nanoparticles with primary particle size below 10 nm and cubic crystalline phase were synthesized by hydrothermal treatment of solutions of zirconyl nitrate, yttrium nitrate and acetylacetone. Before coassembly with polystyrene (PS) microspheres, a dispersant Dolapix CE64 was added to the dialyzed sol of YSZ nanoparticles to render their surface negatively charged. Vertical convective coassembly resulted in 3D ordered YSZ/PS hybrid films, which were inverted at 500 C in air to produce inverse opals. The linear shrinkage of the coatings was in the range 15-20%, below previously reported values for YSZ. The obtained coatings demonstrated pronounced photonic properties and retained their ordered structure after annealing at 1000 C for 2 h. Increasing the filling fraction of crystalline nanoparticles in the templates should enable production of fully functional 3D photonic crystals for applications in high-temperature photonics. © 2013 American Chemical Society. |
