High‐Spatial‐Resolution Surface‐Temperature Mapping Using Fluorescent Thermometry

Abstract

Fluorescent thermometry presents a cheap and efficient alternative for small-scale thermal characterization. The use of dried Rhodamine B (see image) as a probe for surface-temperature mapping is demonstrated. The approach is applied in the evaluation of the temperature distribution along resistively heated micro- and nanowires. The temperature is found to be highly uniform along metal wires on silicon.
