Luminescence nanothermometry with alkyl-capped silicon nanoparticles dispersed in nonpolar liquids

HIGHLIGHTS

• who: NANO EXPRESS and collaborators from the Si NPs prepared by electrochemical etching of bulk Si have been functionalized with alkyl chains (octadecene) for dispersion in NPLs like lubricants for mechanical bearingsTheir potential application as fluorescent nanosensors for temperature measurement in lubricated contact with optical access has been evaluated. The important variation of the fluorescence emission energy with temperature (-0., meV/K) allows simple temperature measurement in squalane. Nevertheless, we have shown that this variation is mainly due to energy exchange between Si NPs promoted by viscosity reduction when the temperature is increased. For static condition in . . .
