摘要: Abstract We have synthesized fluorescent yttrium-based fluoride nanoparticles doped with Er 3+ and Yb ions. The nanocrystals, whose size can be adjusted from a few tens to hundreds of nanometers, exhibit strong temperature-dependent fluorescence that makes them excellent candidates for nanoscale thermometry in the (25–100 °C) range. temperature is determined by monitoring intensity ratio two visible lines are thermal equilibrium. discuss sensitivity such probes show they indifferently excited at several wavelengths blue near-infrared part electromagnetic spectrum which high potentials many experimental environments.
