Abstract: YF3: (Eu3+, Nd3+) nanoparticles (orthorhombic phase, D~130 nm) were synthesized via the
co-precipitation method, with subsequent hydrothermal treatment and annealing. The Eu3+ decay
linearly descends with the increase of temperature in the 80–320 K range. The decay (T) slope values
of the annealed YF3: Eu3+ (2.5 and 5.0 mol.%) nanoparticles were the highest (110104 and 67104,
s/K) in the whole 80–320 K range, respectively. Thus, these samples were chosen for further doping
with Nd3+. The maximum Sa and Sr values based on the LIR (IEu/INd) function were 0.067 K1 (at
80 K) and 0.86%K1 (at 154 K), respectively. As mentioned above, the single-doped YF3: Eu3+ (2.5%)
nanoparticles showed the linearly decreasing decay (T) function (5D0–7F1 emission). The main idea
of Nd3+ co-doping was to increase this slope value (as well as the sensitivity) by increasing the rate of
decay (T) descent via the addition of one more temperature-dependent channel of 5D0 excited state
depopulation. Indeed, we managed to increase the slope (Sa) to 180104 K1 at 80 K. This result is
one of the highest compared to the world analogs. |
