Abstract

Abstract : A single nanoplatform integrating laser‐induced heat generation by gold nanoparticles and temperature sensing up to 2000 K via (Gd, Yb, Er)2 O3 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, and Planck's law of blackbody radiation.
