Abstract:
A method for storing information in a three dimensional optical memory storage device, comprising:subjecting a nanocomposite to irradiation, said nanocomposite comprising a matrix of particles of a liquid core resin surrounded by an inner shell resin and an outer shell resin, said outer shell resin forming a continuous phase of the matrix, said particles of liquid core resin containing at least one photosensitive compound and being in an array in said matrix, said continuous phase being substantially free of said photosensitive compound; said irradiation being selectively focused on individual particles in said array to effect photobleaching of said individual particles, said irradiation being two-photon irradiation of a wavelength to effect said photobleaching, and said irradiation being selectively focused on individual particles such that at least one particle adjacent to the selected particle in the direction of irradiation are photobleached by less than 25%.
