Far-field optical nanothermometry using individual sub-50 nm upconverting nanoparticles

We demonstrate far-field optical thermometry using individual NaYF 4 nanoparticles doped with 2% Er 3+ and 20% Yb 3+ . Isolated 20 × 20 × 40 nm 3 particles were identified using only far-field optical imaging, confirmed by subsequent scanning electron microscopy. The luminescence thermometry respons...
