Pudovkin, M. S., Ginkel, A. K., & Lukinova, E. V. (2021). Temperature sensitivity of Nd3+, Yb3+: YF3 ratiometric luminescent thermometers at different Yb3+ concentration. Optical Materials, 119, 111328. |
| Аннотация |
Nd3+ (0.5 mol.%), Yb3+ (1.0, 2.0, 3.0, 4.0, and 8.0 mol.%):YF3 phosphors were synthesized using a coprecipitation
method with subsequent hydrothermal treatment and annealing in vacuum. The Nd3+, Yb3+:YF3
phosphors are orthorhombic phase nano-crystals. Luminescence intensity ratio (LIR) of Nd3+ (4F3/2 – 4I9/2, ~866
nm) and Yb3+ (2F5/2 – 2F7/2, ~980 nm) emissions was chosen as temperature-dependent parameter. The energy
exchange between 4F3/2 (Nd3+) and 2F5/2 (Yb3+) is phonon-assisted which explains the temperature dependence
of LIR. There are Nd3+ to Yb3+ energy transfer (ET), Yb3+ to Nd3+ back energy transfer (BET) and energy
diffusion (ED) between Yb3+ ions. The probability of BET decreases with the increase of Yb3+ concentration
which leads to LIR dependence on Yb3+ concentration. The maximum absolute temperature sensitivity (Sa) was
achieved for Nd3+ (0.5%), Yb3+ (1.0%):YF3 (Sa = 0.0018 K 1 at 148 K). The studied samples demonstrate high
stability after 8 cooling-heating cycles. The Nd3+ (0.5%), Yb3+ (1.0%):YF3 phosphors are very promising for
temperature sensing. |
