A versatile approach for coating oxidic surfaces with a range of nanoparticulate materials

Abstract

A versatile and effective method by which a wide range of nanoparticulate materials can be attached to a variety of oxidic surfaces is presented. After synthesizing the nanocrystals (PbS, CdSe, CdSe@CdS core–shell, Au) via standard hot injection routes, the stabilizing ligands are exchanged to 3-mercatopropyl-trimethoxysilane (MPTMS). The ligand exchange is monitored using FTIR-spectroscopy and transmission electron microscopy (TEM). The modified nanocrystals were then applied to different oxidic substrates, yielding homogeneous and dense particle films. The effectiveness of this coating procedure is subsequently compared with the commonly employed deposition methods by means of electrochemical measurements and scanning electron microscopy imaging and found to be vastly superior in its particle deposition efficiency. The applicability of this methodology is further verified by depositing a layer of PbS nanoparticles onto a silica sphere colloidal crystal to modify its optical properties.
