Surface plasmon coupled light emitter by the nanofabricated structures for display devices

Abstract

The plasmonic enhancement from the light emitter in close proximity to the metallic nanostructures for highly efficient display applications was investigated through the photoluminescence and cathodoluminescence measurements. Through plasmon resonance driven by light-matter interaction, AC plasma display panel and transparent plasma display panel with high luminous efficacy were developed in this work. The luminescence enhancement from the light emitter using the surface plasmon resonance has been mainly well-known for the part of research areas related to the biological application. The fluorescent dye in close proximity to the metal nanoparticles shows the stronger fluorescence intensity than the nature of its. Therefore, this enhancement phenomenon has been novel solution to detect the fluorescence signal. Recently, this concept is expanded to the organic single molecule, quantum dot, and semiconductors. The some researches showed the enhanced luminescence from the organic single molecule, quantum dot, and semiconductor. There are the reports on implementing the high efficient devices using the organic single molecule and semiconductor incorporating the surface plasmon. However, these lighting materials show the small strokes shift and have the poor color purity due to the wide emission bandwidth. Even with the inclusion of display devices based on OLEDs and semiconductor LEDs, the use of surface plasmon resonance has not yet been reported in the display industry. We have investigated the rare-earth metal ions as the light emitter instead of the organic molecule and semiconductor. We have studied how the surface plasmon resonance can affect and modify the radiative transition governed by electric-dipole transition and magnetic-dipole transition in rare-earth metal ion. Eventually, the present work applied the surface plasmon resonance to large-scale and commercial display devices. The rare-earth ions such as Eu, Tb, and Dy show the large strokes shift and h...
