Abstract

original image

A nanoplatform accomplishes simultaneous laser-induced heat generation by gold nanoparticles and temperature sensing by (Gd,Yb,Er)2O3 nanorods, presenting considerable potential for hyperthermia and deep-tissue optical imaging. On page 4868, Luis D. Carlos, J. Rocha and co-workers assess the local temperature from the Boltzmann distribution of the Er3+ up-conversion 2H11/24|15/2/4S3/24|15/2 intensity ratio (300–1050 K) or Planck's law for white-light emission (1200–2000 K).
