A substance that absorbs light and so promotes a chemical reaction, without changing its own characteristics.
Various phenomena arise when a TiO2 (titanium oxide) photo catalyst absorbs ultra-violet light.

Sputtering approach is superior to the wet method in the following ways:

• Strong film! → Long lasting characteristics
• Uniform film thickness → Beautiful finish (managed at nanometer level)
• Easy automation of the manufacturing process.
• Quick equipment start-up.
• Simplified production system.
