Advanced Luminescent Core/Shell Temperature Sensors for Use in Explosions

摘要

Extracting information about temperature as a function of time in an explosive fireball requires a kinetic analysis of our luminescent nanoparticles. We previously performed an initial evaluation of the temperature dependence of (crystalline Tb:ZrO2)/ (precursor Eu:Y2O3) core/shell nanoparticles. We continued our investigation of these nanoparticles as potential thermosensors by exploring the optical properties as a function of temperature and time. The Johnson-Mehl-Avrami-Kolmogorov (JMAK) model is used to fit our data.
