Quantum dot/liquid crystal nano-composites are promising new materials for a variety of applications in energy harvesting, displays and photonics including the liquid laser. To realize many applications, however, we need to control stabilize nano-particle dispersion different host phases understand how particles behave an anisotropic fluid. An ideal system will allow controlled assembly either well-defined clusters or uniform particle distribution. In this paper, investigate mesogen-functionalized quantum dots cholesteric crystal. These nanoparticles known assemble into dense stable packings nematic phase, such structures, when localized defects, can potentially enhance coupling between cavity. Controlling using mesogenic surface ligands, demonstrate resonant fluid photonic cavities result from co-assembly luminescent presence crystalline ordering.
