heal.abstractPbI2 semiconductor quantum wires have been synthesized in the interlayer space of montmorillonite organic modified clays by simple intercalation reactions. The experimental results showed that the quantum wires have been retained within the lamellar space of layer silicates exhibiting a well-defined diameter and narrow length distribution. The synthetic procedure involves chemical reactions within the clay interlayer, which are achieved through a slow mass transport between the clay platelets via a low solubility path between two different lead iodide phases. The structure and properties of the hybrid composites have been studied by means of X-ray diffraction, energy dispersive spectroscopy, Transmission electron microscopy, optical absorption and photoluminescence experiments. The experimental techniques have verified that the resultant organo-clay-semiconductor composite contains within the clay platelets nano sized low dimensional semiconductor species in the form of wires that exhibit well defined energy gap absorption peaks, which are blue shifted due to quantum confinement phenomena.en
