a reaction medium. It was found that the amount of the PbI2 component could be controlled, to some extent, by varying the amount
of water used. Further, this simple bicomponent precursor-based synthetic
route can be extended to prepare other lead-containing nanocomposites
such as Pb3O4/PbI2 and PbSe/PbI2. Because of the heavy-atom effect, PbS/PbI2 nanocomposites
exhibited good and composition-dependent electrogenerated chemiluminescence
(ECL) performance, demonstrating their potential in the development
of novel ECL sensors for analytical and clinical applications. These
interesting findings would encourage us to gain deep insight on these
phenomena, which could lead to the further development of these new
inorganic materials and their applications.
