STUDY OF INFLUENCE OF ETCHING TIME AND DEPOSITION TIME TO THE STRUCTURE, MORPHOLOGY AND OPTICAL PROPERTIES OF ZINC OXIDE THIN FILMS
Chemical Bath Deposition of ZnO thin films on unetched and etched glass substrate have been done. Etching time of 0,5, 10, and 15 seconds, and deposition time of 0.5, 1, 2, 3 hours were used for growing ZnO in zinc nitrate dan hexamethyl tetraamine mixed solution. The films were characterized by...

| Summary: | Chemical Bath Deposition of ZnO thin films on unetched and etched glass
substrate have been done. Etching time of 0,5, 10, and 15 seconds, and deposition
time of 0.5, 1, 2, 3 hours were used for growing ZnO in zinc nitrate dan hexamethyl
tetraamine mixed solution.
The films were characterized by X-Ray Diffraction, Scanning Electron
Microscopy, and Spectrophotometry method to reveal their structure, morphology
and optical properties.
It is found that the optimized ZnO film was deposited on 5 second etched glass
substrate for one hour. The etched substrate surface facilitated for crystalitation and
growing ZnO film. The deposited ZnO film was ball-like crystalline grain staggered
on glass substrate, peaked at (100) plane with 78% transmittance in the visible light
range and the optical band gap of 4.12 eV. |
