摘要

The effect of a two-dimensional Y_2O_3:Eu~(3+) photonic crystal (PC) pattern on the extraction efficiency of photoluminescence from the underlying Y_2O_3:Eu~(3+) thin-film phosphor was investigated. The photonic crystal structure was fabricated using a direct nano-imprint process with a Pechini-type Y_2O_3:Eu~(3+) sol as the nano-imprint resin and a patterned polydimethylsiloxane (PDMS) stamp as the mold. The elevated pressure and temperature of the nano-imprinting process converts the Y_2O_3:Eu~(3+) sol into a Y_2O_3:Eu~(3+) gel resulting in high definition transfer of the 2D patterns of the master template into the gel on top of the Y_2O_3:Eu~(3+) thin-film phosphor layer. The extraction efficiency of the 2D Y_2O_3:Eu~(3+) gel PC-assisted Y_2O_3:Eu~(3+) thin-film phosphor was approximately 3.7 times higher than a non-PC Y_2O_3:Eu~(3+) gel coated Y_2O_3:Eu~(3+) thin-film phosphor.
