Temperature Imaging around Plasmonic Structures

Abstract

In the course of this work a novel microscope was constructed that is able to obtain a temperature map on the micro and nanoscale. The principle is demonstrated by presenting thermal maps of heated gold micro and nano structures. The temperature measurement is based on a uorescence polarization anisotropy measurement, and can produce a thermal image at a fast frame rate, which allows to obtain a thermal video. Being an all optical based method, it allows for high resolution and robust measurements in very short times. The limitations and noise contributors to the system were analyzed and presented. This technique opens new perspectives in medicine, nanoelectronics, nano uidics and othe
