| Outline of Final Research Achievements |
Polymer array waveguide grating upconversion luminescent (UL) devices for the fabrication of transparent displays from a projection system to a non-projection system were prepared. First, rare-earth-ion-doped ceramic nanoparticle films were patterned by micromolding in capillaries, resulting in the formation of dot arrays of UL layers with a diameter of 50 micrometers on supporting substrates. Next, line and space arrayed waveguides at a width of 50 micrometers was formed on the UL layers using low refractive index silicone molds and high refractive index monomers. After photopolymerization, UL layers were immobilized on the waveguides. A second arrayed waveguides were fabricated perpendicular to the first waveguides. The UL layers was at the intersection of the first and second layer waveguides. Irradiation of near infrared light at 1,500 nm from the first layer waveguides and at 808 nm from the second layer waveguides excited selectively the UL layers at the intersection.
