LASER PATTERNING OF ORGANIC ELECTROLUMINESCENT DEVICES

THE OVERALL OBJECTIVE OF THIS RESEARCH PROJECT IS TO DEVELOP MULTICOLOR THIN FILM ELECTROLUMINESCENT DEVICES. THE KEY TO ACHIEVING HIGH BRIGHTNESS AND EFFICIENCY IS THE USE OF A NEW CLASS OF LUMINESCENT ORGANOMETALLIC LANTHANIDE COMPLEXES AS EMITTER MATERIALS AND NEW MATERIALS FOR ELECTRON AND HOLE INJECTION. EFFICIENT INJECTION TYPE THIN FILM ELECTROLUMINESCENT DEVICES REQUIRE ELECTRON AND HOLE INJECTING MATERIALS WITH LOW AND HIGH WORK FUNCTIONS RESPECTIVELY . BY USING ORGANIC HOLE CONDUCTORS AND ALKALI METAL ALLOYS AS ELECTRON INJECTORS, IT WILL BE POSSIBLE TO DEVELOP ELECTROLUMINESCENT DEVICES OF HIGH BRIGHTNESS AND CONTRAST FOR MULTICOLOR FLAT PLATE DISPLAYS. HIGH RESOLUTION DISPLAYS WILL BE FABRICATED USING LASER PATTERNING OF THE ELECTRODES. ANTICIPATED BENEFITS/POTENTIAL APPLICATIONS - THIS RESEARCH WILL LEAD TO A NEW GENERATION OF ELECTROLUMINESCENT DISPLAYS FOR INSTRUMENTS, TELEVISION AND COMPUTERS.
