Enhanced luminescence, collective heating, and nanothermometry in an ensemble system composed of lanthanide-doped upconverting nanoparticles and gold nanorods

A combined system of gold nanorods and NaGdF4:Er3+/Yb3+ upconverting nanoparticles with double functionality, luminescence enhancement, and monitored heating is introduced. The paired nanostructures could become an excellent optical heater with thermal probe incorporated. To study their interaction,...

The paired nanostructures could become an excellent optical heater with thermal probe incorporated.

Gold nanorods create a localized electromagnetic field that enhances the emission intensity from upconverting nanoparticles.

The temperature can be controlled by changing the excitation power and measured in situ via the Er3+ thermally sensitive luminescence. At high excitation powers, the heating can trigger a deformation of the gold nanorods, which limits the maximum temperature achievable in the system to 160 °C.
