Abstract:

A glass with a honeycomb surface was prepared by a reverse micellar solution etching technology. The honeycomb surface might reduce the light reflection and increase the average transmittance of visible light by nearly 7%. The chemical etching technology is environment friendly for unuse of HF or fluosilicate. To compare the visible light transmittance of the coated glass, CeO2/TiO2 films were deposited on the honeycomb surface glass and raw glass by radio frequency magnetron sputtering. A series of optimization experiments were carried out to obtain a coated glass with high visible transmittance and high UV cut-off. The samples were characterized by UV-Vis spectrophotometer, SEM, XRD, and XPS. When the UV cut-off ratios were 99% for both the honeycomb surface glass and the raw glass, the average transmittance of visible light was 85% for the coated honeycomb surface glass, and only 79% for the coated raw glass prepared under the same coating conditions. In addition, the porous structure on the glass surface also improved the contact area between the film and the substrate. Therefore, the binding force between film and substrate was increased by about 2 times.

Key words: porous glass, transmittance, CeO2/TiO2 coating, magnetron sputtering
