Title: Using Lanthanides to Measure Temperature
Abstract: The optical properties of lanthanide ions can be used to determine temperature. We have used two different approaches: (1) Eu3+’s ability to probe its local environment and (2) 2-color fluorescence (Dy3+ and Sm3+) to determine temperature under extreme conditions. I will describe three research projects that have used these approaches to measure temperature in detonation environments and in composites under dynamic compression.
