▎ 摘　　要

Graphene oxide (GO)-ZnO quantum dots (QDs) thin film electrode was prepared by the deposition of ZnO QDs through spin coating over the surface of electrophoretic deposited (EPD) GO on FTO substrate. The interaction of ZnO QDs with GO surface was confirmed by the crystalline, structural and optical properties of GO-ZnO QDs thin film. The prepared GO-ZnO QDs thin film was utilized as working electrode in chemical sensor for the low level detection of ethyl acetate (EA). GO-ZnO QDs thin film electrode based EA chemical sensor exhibited substantially high sensitivity of similar to 16.035 mA mM(-1) cm(-2), the limit of detection (LOD) of similar to 26 mu M, limit of quantification (LOQ) of similar to 80 mu M with correlation coefficient (R) of similar to 0.97879.
