Abstract

Laser Induced Fluorescence (LIF) was investigated for the potential use of full-field temperature measurements in high-temperature molten salt applications. The fluorescent spectra of Tb³⁺, Eu³⁺, and Dy³⁺ were measured using fiber optic spectroscopy in order to study the temperature dependence of lanthanides in the molten LiF-NaF-KF (FLiNaK) salt. Dy³⁺ showed to be the most suitable tracer for high-temperature molten salt applications due to its distinguishable primary peak at temperatures up to 700 °C.
