- Photonic crystals;
The generation of spherical colloids of titania with uniform diameters (see Figure for an SEM image) has been achieved using a new precursor. By varying the concentration of titanium glycolate in acetone the diameter of these spherical colloids could be controlled in the 200–500 nm range. The as-synthesized colloids could also be readily assembled into 3D crystalline lattices with qualities sufficiently good for optical characterization.
