Optical Absorption Measurement of Synthesized ZnO using Ultra Violet-Visible Spectrophotometer

Nagla El Badri Mohammed Saeed El Badri | Kamal Mahir Sulieman


Abstract: Zinc oxide (ZnO) is characterized by its unique electrical and optical properties. It is a future substance and promising compound which can be applied in different structures and used to fabricate different devices. The main objective of this work is to investigate the optical properties of ZnO annealed at 1000OC in muffle furnace for 3, 6 and 9hours. The annealed samples were Zinc, Zinc sulphide and zinc sulphate, where commercial zinc oxide was used as a control sample. The oxidized ZnO samples were dispersed in an absolute ethyl alcohol with ultrasonic wave. The excitonic peaks of the prepared ZnO samples appeared at 229.99 and 207.51 nm. The excitonic absorption of Zn samples annealed at 1000oC for 3, 6, and 9 h represented the strongest and sharp peaks around 229.99 nm. The absorbance values spectra of ZnSO4 samples annealed at 1000oC for 3 h represented a higher value of 0.89 au as compared with the control and other samples. These results indicated that high temperature for a long time will improve the electrical and optical properties of ZnO samples obtained from different sources.
