A nanoplatform accomplishes simultaneous laser‐induced heat generation by gold nanoparticles and temperature sensing by (Gd,Yb,Er) 2 O 3 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 Er 3+ up‐conversion 2 H 11/2 → 4 | 15/2 / 4 S 3/2 → 4 | 15/2 intensity ratio (300–1050 K) or Planck's law for white‐light emission (1200–2000 K).
