New technique pinpoints nanoscale ‘hot spots’ in electronics to improve their longevity

Researchers from the University of Rochester have outlined a process for mapping heat transfer using luminescent nanoparticles. By applying highly doped upconverting nanoparticles to the surface of a device, the researchers were able to achieve super-high-resolution thermometry at the nanoscale level from up to 10 millimeters away. According to Andrea Pickel , one of the scientists involved in the study, this method could be used by manufacturers to improve a wide array of electrical components.
