Neodymium(III) doped fluoride nanoparticles as non-contact optical temperature sensors

Dominika Wawrzynczyk et al. Nanoscale. .

Abstract

We report that non-contact optical temperature sensing can be achieved with the use of heavily Nd(3+) doped NaYF(4) nanoparticles. The temperature evaluation can be realized either by monitoring the absolute luminescence intensity or by measuring the intensity ratio of the two Stark components of the (4)F(3/2) multiplet in the Nd(3+) ions.
