    摘要: An optical data store is specified, having a data storage layer with a non-toxic and biodegradable polymer as light-sensitive storage medium which has photo-inducible anisotropy, for the induction of which a threshold value of the optical intensity has to be exceeded. The light-sensitive material is preferably bacteriorhodopsin which, by way of example, is immobilized in a manner embedded in a suitable matrix material or, if appropriate, in a crosslinked manner. The storage medium permits a high storage density and can be applied in a simple manner, for instance by printing onto a substrate.

    摘要: This invention relates to the field of materials of the photorefractive crystal. The composition of these crystals is Li1−xNb1+yO3: Fem, Mn, where M can be magnesium, indium, or zinc; when using q to denote the ion valence of M (q=2 when M is Mg or Zn, and q=3 when M is In), the values of x, y, m, and n are in the range of 0.05≦x≦0.13, 0.00≦y≦0.01, 5.0×10−5≦m≦7.5×10−4, and 0.02≦qn≦0.13. This invention greatly improves the photorefractive properties of LiNbO3 crystals: makes it have a high diffraction efficiency (more than 68%), a fast response speed for photorefraction (an order of magnitude faster than iron doped LiNbO3), and a high resistance to optical scattering (the light intensity threshold to photorefractive fan scattering near two orders of magnitude larger than LiNbO3: Fe). This invention is an excellent three-dimensional optical storage material and has a vast potential market.
