Zusammenfassend haben wir in dieser Studie nicht nur erfolgreich demonstriert, dass planare und 3-dimensionale plasmonisch-aktive Gold-Nanostrukturen via FEBID verl\u00e4sslich\u00a0hergestellt, sondern insbesondere fein abgestimmt werden k\u00f6nnen, um Resonanzen bei gew\u00fcnschten Wellenl\u00e4ngen und r\u00e4umlichen Positionen zu erzeugen. Als Modellsysteme werden planare Au-Nanodr\u00e4hte und 3D-Nanospitzen verschiedener Geometrien mittels FEBID gedruckt und deren plasmonische Aktivit\u00e4ten durch STEM-EELS-Messungen charakterisiert. Die Ergebnisse werden durch entsprechende Simulationen mithilfe der MNPBEM-Toolbox erg\u00e4nzt, welche eine sehr gute \u00dcbereinstimmung mit den experimentellen Daten zeigen.\u00a0Dadurch ist es m\u00f6glich, die optische Aktivit\u00e4t hinsichtlich der r\u00e4umlichen Positionen als auch der Wellenl\u00e4ngen pr\u00e4zise einzustellen. Dieser Proof-of-Concept ebnet nun den Weg f\u00fcr das deduktive Upfront-Design noch weit komplexerer freistehender 3D-Nanoarchitekturen, um anwendungsbezogene Zielspezifikationen zu erf\u00fcllen, ohne zeitaufw\u00e4ndige, induktive Trial-and-Error-Ans\u00e4tze durchzuf\u00fchren.[\/vc_column_text][\/vc_column_inner][vc_column_inner column_padding=“no-extra-padding“ column_padding_tablet=“inherit“ column_padding_phone=“inherit“ column_padding_position=“all“ column_element_direction_desktop=“default“ column_element_spacing=“default“ desktop_text_alignment=“default“ tablet_text_alignment=“default“ phone_text_alignment=“default“ background_color_opacity=“1″ background_hover_color_opacity=“1″ column_backdrop_filter=“none“ column_shadow=“none“ column_border_radius=“none“ column_link_target=“_self“ overflow=“visible“ gradient_direction=“left_to_right“ overlay_strength=“0.3″ width=“1\/6″ tablet_width_inherit=“default“ animation_type=“default“ bg_image_animation=“none“ border_type=“simple“ column_border_width=“none“ column_border_style=“solid“][\/vc_column_inner][\/vc_row_inner][vc_row_inner column_margin=“default“ column_direction=“default“ column_direction_tablet=“default“ column_direction_phone=“default“ text_align=“left“ row_position=“default“ row_position_tablet=“inherit“ row_position_phone=“inherit“ overflow=“visible“ pointer_events=“all“][vc_column_inner column_padding=“no-extra-padding“ column_padding_tablet=“inherit“ column_padding_phone=“inherit“ column_padding_position=“all“ column_element_direction_desktop=“default“ column_element_spacing=“default“ desktop_text_alignment=“default“ tablet_text_alignment=“default“ phone_text_alignment=“default“ background_color_opacity=“1″ background_hover_color_opacity=“1″ column_backdrop_filter=“none“ column_shadow=“none“ column_border_radius=“none“ column_link_target=“_self“ overflow=“visible“ gradient_direction=“left_to_right“ overlay_strength=“0.3″ width=“1\/6″ tablet_width_inherit=“default“ animation_type=“default“ bg_image_animation=“none“ border_type=“simple“ column_border_width=“none“ column_border_style=“solid“][\/vc_column_inner][vc_column_inner column_padding=“no-extra-padding“ column_padding_tablet=“inherit“ column_padding_phone=“inherit“ column_padding_position=“all“ column_element_direction_desktop=“default“ column_element_spacing=“default“ desktop_text_alignment=“default“ tablet_text_alignment=“default“ phone_text_alignment=“default“ background_color_opacity=“1″ background_hover_color_opacity=“1″ column_backdrop_filter=“none“ column_shadow=“none“ column_border_radius=“none“ column_link_target=“_self“ overflow=“visible“ gradient_direction=“left_to_right“ overlay_strength=“0.3″ width=“1\/3″ tablet_width_inherit=“default“ animation_type=“default“ bg_image_animation=“none“ border_type=“simple“ column_border_width=“none“ column_border_style=“solid“][image_with_animation image_url=“10718″ image_size=“full“ animation_type=“entrance“ animation=“None“ animation_movement_type=“transform_y“ hover_animation=“none“ alignment=““ border_radius=“none“ box_shadow=“none“ image_loading=“default“ max_width=“100%“ max_width_mobile=“default“][vc_column_text]Das Paper ist hier verf\u00fcgbar: https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/adfm.202310110<\/a><\/p>\n

Plasmonisch-aktive Nanopartikel besitzen die F\u00e4higkeit Licht in hochverst\u00e4rkten, optischen Nahfeldern zu b\u00fcndeln, weswegen sie heute bereits in vielen Bereichen wie zB der Sensorik, Optoelektonik, Katalyse oder Quantentechnik Anwendung finden. \u00a0F\u00fcr die Ausbildung und St\u00e4rke der lokalisierten plasmonischen Resonanzen sind vor allem Material, Geometrie und Gr\u00f6\u00dfe ausschlaggebenden Faktoren. Bisherige Studien beschr\u00e4nken sich dabei haupts\u00e4chlich auf planare Systeme, da 3-dimensionale plasmonisch-aktive Nanostrukturen mit herk\u00f6mmlichen Lithografieverfahren nicht herstellbar sind. Eine zuverl\u00e4ssige plasmonische Modenentwicklung in alle 3 r\u00e4umliche Richtungen erm\u00f6glicht aber nicht nur ein tieferes Verst\u00e4ndnis plasmonischer Effekte, sondern k\u00f6nnte auch durch vertikale und horizontale Modenkopplung einen bedeutenden Einfluss auf zuk\u00fcnftige optische Technologien haben. Gegenw\u00e4rtig arbeiten wir an den M\u00f6glichkeiten f\u00fcr hochkomplexe Strukturen, welche in Zukunft f\u00fcr gezielte Anwendungen verwendet werden sollen.[\/nectar_highlighted_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner column_margin=“default“ column_direction=“default“ column_direction_tablet=“default“ column_direction_phone=“default“ text_align=“left“ row_position=“default“ row_position_tablet=“inherit“ row_position_phone=“inherit“ overflow=“visible“ pointer_events=“all“][vc_column_inner column_padding=“no-extra-padding“ column_padding_tablet=“inherit“ column_padding_phone=“inherit“ column_padding_position=“all“ column_element_direction_desktop=“default“ column_element_spacing=“default“ desktop_text_alignment=“default“ tablet_text_alignment=“default“ phone_text_alignment=“default“ background_color_opacity=“1″ background_hover_color_opacity=“1″ column_backdrop_filter=“none“ column_shadow=“none“ column_border_radius=“none“ column_link_target=“_self“ overflow=“visible“ gradient_direction=“left_to_right“ overlay_strength=“0.3″ width=“1\/1″ tablet_width_inherit=“default“ animation_type=“default“ bg_image_animation=“none“ border_type=“simple“ column_border_width=“none“ column_border_style=“solid“][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"
