  • Methods of obtaining a titanium dioxide nanofilm or microfilm are provided herein. A pure sheet of titanium is irradiated with a CO2 laser to produce the titanium dioxide nanofilm or microfilm. The titanium sheet can optionally be doped with an oxide, such as barium oxide. The method produces titanium dioxide nanofilms or microfilms that can be produced in more than one phase, such as a rutile phase, an anatase phase, or both combined. The titanium dioxide nanofilms or microfilms can be directly fabricated with high purity without any further processing.
