On Photostability of Acrylate and Polymethylmetacrylate Planar-Fiber Structures with Coumarin 7, 47, and 120, POPOP, and NOL8 Luminophores for UV Information Systems

We studied the photostability of planar-fiber structures in the form of films with a thickness of 600–800 µm under long-term ultraviolet irradiation. The films were made of highly pure polymethylmethacrylate (PMMA) and acrylic resin and doped with Coumarin 7, 47, and 120, POPOP, and NOL8 luminophore...

Description
Summary:We studied the photostability of planar-fiber structures in the form of films with a thickness of 600–800 µm under long-term ultraviolet irradiation. The films were made of highly pure polymethylmethacrylate (PMMA) and acrylic resin and doped with Coumarin 7, 47, and 120, POPOP, and NOL8 luminophores. Luminophore NOL12 (KNL12) was in polymer fibers produced by the Technological Center of Polymer Optical Fiber (Russia). PMMA optical fibers were attached to the ends of the films; the luminescence radiation power was measured from the output of these PMMA fibers as a function of the UV irradiation power and time. The prospects of using Coumarin-type luminophores in planar-fiber structures in UV information systems as receiving antennas for optical telecommunications and optical sensors for monitoring physical fields are demonstrated.
