Enhanced light extraction from Y2O3: Eu3+ phosphor films via vacuum nano-imprint lithography using spin-on dielectric materials
This paper reports a simple process to enhance the extraction efficiency of photoluminescence from Eu-doped yttrium oxide (Y2O3: Eu3+) thin-film phosphor. The two-dimensional (2D) SiO2 photonic crystal layer was fabricated by vacuum nano-imprint method using a conventional spin-on dielectric solutio...

| description | This paper reports a simple process to enhance the extraction efficiency of photoluminescence from Eu-doped yttrium oxide (Y2O3: Eu3+) thin-film phosphor. The two-dimensional (2D) SiO2 photonic crystal layer was fabricated by vacuum nano-imprint method using a conventional spin-on dielectric solution as a nano-imprint resin and a 2D patterned Si stamp. The applied pressure and temperature of the patterning and annealing process facilitates the conversion of the spin-on dielectric solution into a SiO2 hemisphere structure resulting in high definition transfer of the 2D reverse pattern of the Si mold. The light extraction efficiency of the Y2O3: Eu3+ thin-film phosphor assisted by 2D SiO2 photonic crystal layer was approximately 1.72 times higher than that of the conventional Y2O3: Eu3+ thin-film phosphor.
•Convenient nano-imprint on two-dimensional photonic crystals is proposed.•Direct patterning process of inorganic material was achieved by sol–gel transition.•The photonic crystal improved light extraction of the thin-film phosphor. |
