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 2H11/2→4|15/2/4S3/2→4|15/2 intensity...
A single nanoplatform integrating laser‐induced heat generation by gold nanoparticles and temperature sensing up to 2000 K via (Gd,Yb,Er)2O3 nanorods is demonstrated, which presents considerable potential for nanoscale photonics and biomedicine. Blackbody emission is ascertained from the temperature increment with AuNP concentration, emission color coordinates as a function of the laser pump power,...
