Titanium dioxide is the most widely used semiconductor substance as a photocatalytic material in self-cleaning surfaces, air and water purification systems, sterilization, hydrogen evolution, and photoelectrochemical conversion. In this work, we propose a photocatalysis effect-based optical information recording on the titanium dioxide nanoparticles and luminescent dye-doped polymer nanocomposite for the first time. The optical information was recorded as holographic gratings. Holographic and non-holographic methods were employed to record optical information on a polymer nanocomposite. A green laser beam and a halogen-tungsten lamp with a band-pass filter were used for this purpose. As a result, the high-density optical information was obtained, with an optical density of 500 mm⁻¹. The data recorded on the polymer nanocomposite is stable and durable.
