Abstract

A series of polyvinyl alcohol (PVA)–selenide nanocomposites, including PVA–Ag₂Se, PVA–Cu_2 − xSe, PVA–ZnSe and PVA–PbSe, were successfully prepared at room temperature and ambient pressure via a simple one-step solution growth technique. X-Ray diffraction (XRD), transmission electron microscopy (TEM) and infrared spectroscopy (IR) were used to characterize the final products. The TEM results showed that the Ag₂Se particles were well dispersed in the polymer matrix and uniform in shape, while those of Cu_2 − xSe, ZnSe and PbSe showed a certain level of aggregation. A possible mechanism for the growth of selenide nanocrystals is discussed.
