The implantation energy and dose were 100 keV and 1.3×1014 cm-2, respectively. The peak implanted region was estimated to be 24 nm from the top of pillars according to the Monte Carlo simulation code TRIM, and the pillar length was measured to be 510 nm by scanning electron microscopy. Intensity of two emission peaks at 650 nm and 652 nm, which were attributed to 3P0-3F2 transition in the 4f-shell, was analyzed by a home build confocal microscopy. It was shown that the photon emission intensity from Pr3+ ions strongly depended on the nanopillar structures and sizes, and the enhancement more than 20-fold was achieved compared to the non-structured region. The luminescence lifetime was independent of nanopillar structures and sizes. These results indicate that the absorption efficiency of incident photons and the photon extraction efficiency were enhanced by the confinement in nanopillars.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"4th QST International Symposium","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sato, Shinichiro"}],"nameIdentifiers":[{"nameIdentifier":"922221","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Li, Shuo"}],"nameIdentifiers":[{"nameIdentifier":"922222","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Deki, Manato"}],"nameIdentifiers":[{"nameIdentifier":"922223","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishimura, Tomoaki"}],"nameIdentifiers":[{"nameIdentifier":"922224","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Hirotaka"}],"nameIdentifiers":[{"nameIdentifier":"922225","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nitta, Shugo"}],"nameIdentifiers":[{"nameIdentifier":"922226","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Honda, Yoshio"}],"nameIdentifiers":[{"nameIdentifier":"922227","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"C.
