Holographic Recording in Micron Films Based on Polyfluorochalcones

Optical properties and features of holographic recording upon photopolymerization of thin (about 1 μm) films based on acrylamide derivatives of polyfluorochalcones on a glass substrate have been investigated. The spectral sensitivity regions (350–400 nm) and refractive index ( n = 1.647) of the film...

Description
Summary:Optical properties and features of holographic recording upon photopolymerization of thin (about 1 μm) films based on acrylamide derivatives of polyfluorochalcones on a glass substrate have been investigated. The spectral sensitivity regions (350–400 nm) and refractive index ( n = 1.647) of the films have been determined. It has been shown that these films allow the holographic recording of a diffraction grating with a diffraction efficiency of 59% and a width of the angular selectivity contour of 46° after washing out the nonpolymerized material in an organic solvent.
