Using transmittance electron microscopy, fluorescence and polarizing optical microscopy, optical spectroscopy and fluorescent correlation spectroscopy it was shown that CdSe/ZnS quantum dots coated with a specifically designed surfactant were readily dispersed in nematic liquid crystal to form stable colloids. The mixture of an alkyl phosphonate and a dendritic surfactant, where the constituent molecules contain promesogenic units, enabled the formation of thermodynamically stable colloids that were stable for at least one year. Stable colloids are formed due to minimization of the distortion of the LC ordering around the quantum dots.
