Structural and optical properties of nanocomposited ZnO/SnO2 thin film deposited at different Sn precursor

Abstract

The nanocomposited ZnO/SnO2 thin film were synthesized by thermal chemical vapour deposition (CVD) on ZnO coated glass as template layer. Based on the FESEM observations, different composite nanostructures grew on the ZnO template layer for different Sn precursors; Tin TetraChloride, Dibutyltin Diacetate and Tin Powder. The photoluminescent of nanocomposited ZnO/SnO2 thin film indicated low peak at ultra-violet (UV) emission around 390 nm and high intensity of peak around 590 nm that corresponding to the visible emission.
