    摘要： Articles for recording a hologram are described. The articles include a holographic recording medium having a transparent polymeric binder and a photoreactive dye dispersed therein. The articles also include a first compound, dispersed in the holographic recording medium or disposed over a first surface of the holographic recording medium from which surface the hologram is viewed, that is transparent to light in the wavelength range to which the photoreactive dye is sensitive and which is capable of being converted to a converted compound that is opaque to light in the wavelength range to which the photoreactive dye is sensitive and transparent to light in a different wavelength range for viewing the hologram.

    摘要： The present disclosure relates generally to optical data storage media, and more specifically, to holographic storage media. In one embodiment, an optical storage medium includes a polymer matrix having one or more polymer chains. The optical storage medium also includes a reverse saturable absorption (RSA) sensitizer disposed within the polymer matrix that is configured to become excited upon exposure to light having an intensity above an intensity threshold and configured to transfer energy to a reactant. The optical storage medium also includes a diphenyl cyclopropene (DPCP)-derivative reactant disposed within the polymer matrix and capable of undergoing a modification upon receiving an energy transfer from the excited sensitizer that changes a refractive index of the optical medium.
