Until now, thermal therapies have suffered from a lack of control over the absolute temperature of the treated tissue because the nanothermometers used for thermal feedback, based on a spectral analysis of emitted radiation, were affected by the inhomogeneous extinction of the tissues. This work shows how this deficiency can be overcome by using core-shell-shell nanostructures doped with lanthanide ions (Nd3+ and Yb3+). Thermal reading was achieved from the analysis of the Yb3+ luminescence lifetime whereas simultaneous heating was achieved thanks to the non-radiative deexcitations of Nd3+ ions. Simple proof-of-concept experiments show the great potential of these lanthanide-doped nanostructures for the development of in vivo photo-thermal treatments with absolute and reliable thermal feedback. eng Atribución 3.0 España Lanthanide doped nanoheaters with reliable and absolute temperature feedback journal article URL https://docta.ucm.es/bitstreams/774f767e-2ec4-4720-adbe-98c8dfd608a6/download File MD5 65b41f3e58d58cc3d0bdd12b23d35125 4385012 application/pdf 1-s2.0-S0921452621007961-main.pdf URL https://docta.ucm.es/bitstreams/32945431-1fca-4ac2-aea2-4b382b559397/download File MD5 263aa198d94eecb4b533d03af990fe71 42755 text/plain 1-s2.0-S0921452621007961-main.pdf.txt
