Fluorescent Pattern Generation of Anthracene Polymers by Holographic Technique

Abstract

Photopolymer films were prepared from the mixture of acrylate monomer, binder, a visible light sensitive photo initiator, and fluorescent polymer (polyanthracene, PMAn), to generate the fluorescent patterns by holographic method. The transparent photopolymer films were yellow colored and having maximum fluorescent emission at visible range. The diffraction efficiency of the PMAn doped film with thickness of 100 μm was maximized to 50%. Fluorescent patterns in a submicron/ micron scale were inscribed on the photopolymer film with a visible laser. As a result of the fluorescent grating patterns, the fluorescence of the film was highly enhanced compared to the unpatterned film.
