Abstract
We present a new approach for multi-layered optical data storage in C60 doped polystyrene film. We find that photo- oxidation may increase the fluorescence intensity of C60 molecule by two-photon excitations in a wide wavelength region (780 - 910 nm) from a 100 fs Ti:sapphire laser. The proposed scheme encodes the digital bits by photo-oxidation of C60 induced by two-photon excitation, and reads the increase fluorescence from the oxidation area. The high fluorescence signal can be easily distinguished as bit 1, and low fluorescence signal, as bit 0. This change in the fluorescence intensity could be used to encode information for read-only- memory.
