Far-Field Optical Nanothermometry via Individual Luminescent Nanoparticles

From transistors to LEDs, as device length scales trend downward, poor thermal dissipation increasingly leads to nanoscale hotspots that limit performance. To address this challenge, nanoscale thermometry tools must be developed. Conventional far-field optical methods provide a convenient non-contact approach, but these techniques are fundamentally diffraction limited. This seminar will discuss how we employ the temperature-dependent luminescence of individual nanoparticles to achieve sub-50 nm single-point temperature measurements.
