Self-assembling-photonic-materials-latest-research

This review offers an summary of recent advances in the manufacture and usage of self-assembled photonic crystals (PCs) for laser applications in organic and polymeric materials such as chiral liquid crystals (CLCs) and colloidal crystals (CCs). Both CLCs and CCs have an inherent capability to spontaneously assemble 1D-PC and 3D-PC structures, respectively. When the periodic duration of the PC structures of the CLCs and CCs extends to several hundred nanometers of the light wavelength, the photonic band-gaps (PBGs) may be visualized as representing Bragg colors. The induced laser activity at the PBG band(s) or inside the PBG wavelength may be produced by optical excitation when mixing fluorescence dyes in the CLCs and CCs. In addition, the optically excited laser action is controlled by external stimuli due to the self-organization of CLCs and CCs.
