PHOTOREFRACTIVE COMPOSITION COMPRISING ELECTROLYTES IN A PHOTOREFRACTIVE LAYER AND METHOD OF MAKING THEREOF |
摘要 |
A photorefractive composition and a photorefractive device comprising the composition are disclosed. The composition is configured to be photorefractive upon irradiation by a laser having a wavelength in the visible light spectrum and comprises a polymer, a non linear optical chromophore, a plasticizer, and an electrolyte. In an embodiment, the percentage of polymer recurring units that comprise a charge transport moiety is less than 30%. In an embodiment, the electrolyte comprises one or more of ammonium salts, heterocyclic ammonium salts, and phosphonium salts. In an embodiment, the polymer is selected from the group consisting of polycarbonate, polyurea, polyurethane, poly(meth)acrylate, polyester, polyimide, and combinations thereof. Preferably, the composition has a diffraction efficiency of about 25% or greater upon irradiation with a visible light laser. |
