Disclosed is a method for storing and retrieving information. More specifically, the present invention is a method for forming predetermined patterns, or data structures, using materials which exhibit enhanced absorption of light at certain wavelengths or, when interrogated with a light having a first wavelength, provide a luminescent response at a second wavelength. These materials may exhibit this response to light inherently, or may be made to exhibit this response by treating the materials with ionizing radiation.
