We annealed these films at three different temperatures of 200 o C, 400 o C and 600 o C. The absorption spectra showed that the band gap of the deposited film was about 3.29 eV. So it confirmed that the film was of ZnO. As temperature increased the band gap of the film decreased. Transmittance spectra revealed that the transparency of the film increased with rise in temperature. Different optical constants such as refractive index, film thickness, band gap, transmittance, extinction coefficient and so on were investigated and compared at different temperatures. Ellipsometry revealed that the thickness of the film was 125 nm.

Nanobubble, now directly imaged by tapping mode atomic force microscopy or by dynamic light scattering, were previously inferred from long ranged attraction between hydrophobic surfaces immersed in water. They exists in an interconnected, irregular and closed pack structure whose lifetime is in order of hours and whose morphology is dependent upon the pH. Different forces are responsible for stabilization of micro and nanobubble. These are electric double layer repulsion between neighboring nanobubble[1] while some believe this stability is supported by electrically charged liquid gas interface, which creates forces that prevent bubble coalescence . Furthermore the stability of nanobubble increases when the gas is of Knudsen type .
