Another important method for photonic crystal fabrication employs colloidal particle self-assembly. A colloidal system consists of two separate phases a dispersed phase and a continuous phase (dispersion medium). The dispersed phase particles are small solid nanoparticles with a typical size of 1-1000 nanometers. Colloidal crystals are three-dimensional periodic lattices assembled from monodispersed spherical colloids. The opals are a natural example of colloidal photonic crystals that diffract light in the visible and near-infrared (IR) spectral regions due to periodic modulation of the refractive index between the ordered monodispersed silica spheres and the surrounding matrix.

Fig. 3 illustrates transport properties of NIMs. The light source was produced directly inside ID colloidal photonic crystal by means of excitation of luminescence in several dye doped globules. Each consecutive sphere acts as a micro-lens and focus light of arbitrary spectrum in a highly distorted and laterally squeezed photonic nanojet [6] at its shadow side close to the intersphere contact point. At these locations the intensity maxima appear in Fig. 3b. [Pg.154]

In spite of its simplicity, the long response time of the hydrogel photonic crystal materials has limited their utility as sensors. This is because of the slow diffusion of analytes in the hydrogel to influence the optical properties. New fabrication procedures of these hydrogel photonic crystal sensors were used to improve the response time. The Lee Group [96] demonstrated a mechanically robust and fast responsive photonic crystal pH sensor, which was fabricated by templated photopolymerization of hydrogel monomers within the interstitial space of a self-assembled colloidal photonic crystal, as shown in Fig. 25.

As mentioned earlier, colloidal photonic crystal devices were fabricated through a self-assembly process. This process is the most economic method to produce 3D nanostructures. When the size of a colloidal building block is half the wavelength of visible light, a physical change of the photonic crystals caused by the analytes converts into a color change. However, the width of the reflectance peak is usually broad, which disturbs the high sensitive characterization. [Pg.2407]

Metal containing polyynes are multifunctional materials which combine the properties of organic polymers with those of metal centers coordinated to the organic moiety and are able to form nanotemplates, colloidal photonic crystals, multilayer capsules and hollow vesicles [127, 128], An example of a rod-like polymetallayne self-assembly in hollow nanorods has been recently reported [129] the computer simulations of the nanostructure show that the polymer chains are ordered in parallel lines that give rise to a tubular morphology rather unusual for these materials, but promising for sensor devices applications.
