As semiconductor devices for generative AI become increasingly miniaturized, evaluating heat generation at the nanoscale has become a critical challenge. In this study, we investigated a nanoscale temperature measurement method using the emission spectra of lanthanide nanoparticles supported on silver nanowires. Localized heating was induced by exciting localized surface plasmon resonance (LSPR) in gold nanoparticles, and changes in the emission intensity ratio associated with heat propagation were observed. The experimental results showed good agreement with numerical calculations, demonstrating the potential of this approach for nanoscale thermal sensing.
