Synthesis and optical properties of SnO2–CuO nanocomposite

Abstract

SnO2–CuO nanocomposite was synthesized by impregnating SnO2 nanowires with CuCl2 solution and subsequent calcination. SEM and XRD were used to characterize the morphology and structure of the product. The optical properties were analyzed by Raman and photoluminescence (PL) spectra at room temperature. Except the strong orange emission of SnO2, the PL spectrum showed a red shoulder at 678nm which originated from the interface between SnO2 and CuO.
