In recent years, rare earth ions doped optical materials have been extensively utilized in anticounterfeiting, temperature measurement, and other fields. However, it is difficult for single-mode photoluminescence to meet the increasingly complex anticounterfeiting needs in practice. In this article, Yb 3+ /Er 3+ codoped Y 2 WO 6 multifunctional microparticles have been designed and prepared, which can emit multimode luminescence and are used for anticounterfeiting and temperature measurement. Under excitation at 254, 365, and 980 nm, Y 2 WO 6 :Yb 3+ /Er 3+ microparticles can emit blue, green, and yellow-green luminescence, respectively. The multicolor emission is helpful to improve the security of anticounterfeiting in multimode. In addition, the upconversion, downconversion luminescence, and downconversion lifetime attenuation of this material can be used for fast responsive and noncontact temperature measurement.Among the three temperature measurement methods, the material has the highest sensitivity under the downconversion temperature measurement method, which is 1.25 × 10 -2 K -1 (at 303 K). The results suggest that the Y 2 WO 6 :Yb 3+ /Er 3+ microparticles have excellent applications in the domain of multimode anticounterfeiting and temperature measurement.

“…The fluoride host, hexagonal NaYF 4 (β-NaYF 4 ), is considered as the most efficient host material for green/blue UC phosphors [2,[9][10][11]. However, it suffers from the complexity of the crystal structure, phase, dissolution in aqueous suspension, potential leakage of Ln 3+ /Fions, and cytotoxicity [12][13][14]. On the basis of these factors, Barium molybdate (BaMoO 4 ) is a perfect choice; it has relatively low phonon energy, good physical/chemical stability, and simple crystal structure/ phase, is non-toxic and insoluble in aqueous suspension, admits large lanthanide ions, and enables the influential role of molybdate ions for luminescence [4,[6][7][8]15].…”

Yb3+, Ln3+ (Ln3+ = Er3+/Tm3+, Er3+/Tm3+/Ho3+) doped BaMoO4 micro-octahedrons were synthesized by a hydrothermal process. The as-prepared phosphors were characterized by x-ray powder diffraction, field emission scanning electron microscopy, elemental mapping, energy-dispersive x-ray spectroscopy, x-ray photoelectron spectroscopy, and UV–vis diffuse reflectance spectroscopy. The upconversion luminescence properties of the samples were investigated under 980 nm near infrared excitation. The different concentrations of Er3+, Tm3+, and Ho3+ were used for tuning the multicolor (blue, green, and red) emissions. The multicolor emissions were investigated by Commission Internationale de l’Elcairage chromaticity and decay lifetime. The photon process as well as the energy transfer mechanism between the Yb3+ to Er3+, Tm3+, and Ho3+ were described.

A complete apparatus for luminescence thermometry has been built comprising a programmable hot-plate up to 400 °C, a hot/cold plate 0 °C-80 °C, a control circuit with thermocouple feedback, a platinum resistance thermometer and an oven for calibration. An original design allowed us to build the apparatus for under 100 $, considerably less than for the commercial equipment. The apparatus must be used with an optical fiber bundle attached to a spectrofluorometer. It is tested for stability and on ZrO 2 :Eu 3+ and Nb 2 O 5 :Eu 3+ samples prepared by a plasma electrolytic process. The tests showed the high stability of the temperature-controlled surfaces. The thermometric properties of the investigated material were tested by the luminescence intensity ratio method of 5 D 1 → 7 F 1 and 5 D 0 → 7 F 2 transitions. The calculated relative sensitivities of Nb 2 O 5 :Eu 3+ and ZrO 2 :Eu 3+ are 3.17% K −1 and 3.07% K −1 at 290 K, respectively, and 0.0012 K −1 at 453 K and 0.000 12 K −1 at 445 K are the calculated absolute sensitivity values, respectively. Nb 2 O 5 :Eu 3+ has shown good thermometric properties up to 180 °C, while ZrO 2 :Eu 3+ is a promising temperature sensor phosphor for higher temperature measurements.
