Abstract

This study explores potential of Er{sup 3+}-Yb{sup 3+} doped phosphors for up-conversion luminescence thermometry in the temperature range from 10 K to 300 K. Yttrium oxide nanopowder doped with trivalent ytterbium and erbium ions (Y{sub 1.97}Yb{sub 0.02}Er{sub 0.01}O{sub 3}) was prepared by hydrothermal synthesis as an example. The intensity ratios of up-conversion emissions from thermally coupled {sup 2}H{sub 11/2} and {sup 4}S{sub 3/2} levels of Er{sup 3+} show strong temperature dependence (in the range 150 K–300 K) with much higher relative sensitivity than those reported for thermometry above room temperature with Er{sup 3+}-Yb{sup 3+} based up-conversion materials. The maximal value of relative sensitivity is 5.28%K{sup −1} at 150 K, with temperature resolution ranging from 0.81 K to 0.06 K. In addition, the intensity ratios of emission from thermally non-coupled Er{sup 3+} levels ({sup 2}H{sub 9/2} and {sup 4}F{sub 9/2}) and from {sup 4}S{sub 3/2} also show temperature dependence that can be approximated with an exponential function. With these up-conversion emission ratios, it is possible measure temperature in the range of 10 K to 300 K with excellent sensitivity and resolution.

Combustion synthesis and up-conversion luminescence of La{sub 2}O{sub 2}S:Er{sup 3+},Yb{sup 3+} nanophosphors

Journal Article Hakmeh, Noha; Chlique, Christophe; Merdrignac-Conanec, Odile; ... - Journal of Solid State Chemistry

La{sub 2}O{sub 2}S:Er{sup 3+},Yb{sup 3+} nanocrystalline up-converting phosphors were synthesized by a combustion method at low temperature, using ethanol as pre-ignition fuel and thioacetamide as sulfurizing agent and organic fuel. The phosphors were characterized by powder X-ray diffractometry, scanning electron microscopy, UV/Vis/NIR spectroscopy and fluorescence spectroscopy. Pure and well-crystallized La{sub 2}O{sub 2}S:Er{sup 3+},Yb{sup 3+} nanoparticles, of the order of 50–200 nm, are obtained after a post-treatment in a H{sub 2}S/N{sub 2} flow for 2 h at 1000 °C. The efficient energy transfer from Yb{sup 3+} to Er{sup 3+} results in a strong up-conversion upon excitation at 980 nm. The emissionmore »« less

The impact of ²H_9/2 → ⁴I_13/2 emission from Er³⁺ ions on ratiometric optical temperature sensing with Yb³⁺/Er³⁺ co-doped upconversion materials

Journal Article Xia, Xiaojing; Volpi, Azzurra; Roh, Joo; ... - Journal of Luminescence

Yb³⁺/Er³⁺ co-doped upconversion materials are widely used for luminescence intensity ratio (LIR) thermometry, where the relative intensity ratio of the green luminescence transitions (²H_11/2 ⁴I_15/2 and ⁴S_3/2 ⁴I_15/2 ) of Er³⁺ dopant ions changes with temperature. In this work we report on the impact of an additional transition from the ²H_9/2 level to the intermediate ⁴I_13/2 level, which overlaps with the green luminescence normally used for LIR thermometry. The ²H_9/2 ⁴I_13/2 emission overlaps extensively with the ⁴S_3/2 ⁴I_15/2 emission and is more sensitive to pump power. The wavelength intervals used to integrate both ²H_11/2 ⁴I_15/2 and ⁴S_3/2 ⁴I_15/2 luminescence needmore »« less
