Although the physicochemical properties of hybrid metal-semiconductor nanostructures strongly depend on their size, shape, composition and spatial distribution of each component , the discovery of new synthesis routes for these hybrid nanostructures is becoming more and more important. Several attempts have been made to obtain different architectures from metal-semiconductor nanocomposites, in particular the Au-CdSe heterostructure.1-16In the case of noble metal nanoparticles (NPs) tipped with semi-quantum rods, conductors; Liang et al.1 represent a simple method for the synthesis of Au-AgCdSe hybrid nanorods (NRs) by deposition of silver (Ag) tips on the ends of Au NRs as a seed solution, followed by selenization of the tips silver (Ag). , and the proliferation of CdSe at these sites.1 This method was carried out by controlling the pH value.1 Das et al.2 demonstrate a method to fabricate gold-decorated CdSe nanowires (NWs) based on the chemical method wet 3-5 for use as surface-enhanced Raman spectroscopy (SERS) substrates.2 In this synthesis route, Au NPs prefer to nucleate on lattice defects at the side facets of CdSe NWs, which has a large effect to obtain a homogeneous distribution of Au NPs. on the nanowire.2,5 Bala et al.6 demonstrated an efficient procedure based on phase transfer between aqueous and organic media to form Au tips on cadmium chalcogenide NPs and NRs. This phase transfer process can be carried out in the presence of an organic ligand that acts as a phase transfer agent and reducing agent for Au3+ ions.6 Salant et al.7 modified a hybrid system of metal-tipped semiconductor nanorods known as nano-dumbbells and used the gold tips. as anchor points for self-assembly using simple thiol molecules.7 I...... middle of paper ...... 15, 1047-1056.11.
