Abstract

original image

„Photothermometer“: Ein PAOF-System wurde mit einem Diodenlaser als Energiequelle, einer wässrigen Suspension plasmonischer Nanostrukturen als photothermische Energiewandler und einer Glaskapillare zur Messung der volumetrischen Ausdehnung der Suspension aufgebaut (siehe Bild). Die Suspension konnte in der Kapillare mehr als 30 mm hoch getrieben werden, was sich zur Betätigung eines elektrischen Schalters nutzen ließ.
