Chemical compounds with high upconversion (UC) intensity are still needed for temperature-sensing media based on the fluorescence intensity ratio (FIR) technique of UC materials. In this work, the citrate-based sol−gel method was used to produce Yb 3+ /Er 3+ −Bi 3+ codoped Ba 2 YV 3 O 11 (BYVO) nanophosphors. Using X-ray diffraction, scanning electron microscopy, and transmission electron microscopy, we examined the influence of Bi 3+ ions on the phase structure and morphology of BYVO was examined. Power-dependent photoluminescence (PL) spectroscopy shows how Er 3+ and Yb 3+ transfer energy, and the involved UC mechanism is part of the two-photon stimulation process. Moreover, the improved optical properties of BYVO phosphors were due to the local environment of Er 3+ ions that was modified by the addition of Bi 3+ ions. The emission intensity of these bands is enhanced in the presence of Bi 3+ ions. The FIR method based on Er 3+ thermal coupling level was used to investigate the temperature-sensing performance. The relative sensitivity of the tridoped nanophosphor has been determined to be 1.45% K −1 at 250 K. The incorporation of Bi 3+ could improve the temperature resolution obtained when it is used as a thermometric sensor. The results obtained from the present study indicate that the Er 3+ −Yb 3+ −Bi 3+ tridoped BYVO nanophosphors may be of particular interest in developing near-infrared to visible upconverters, green display devices, and optical nanothermometry.

“…Yao et al construct quantum dots modified NaYF4:Yb 3+ , Ho 3+ nanophosphors for dual-channel anti-counterfeiting ink printing [7] [11]. For upconversion, Er 3+ , Ho 3+ , Tm 3+ ions are widely used as activators and Yb 3+ ions are generally combined with them for sensitizing due to the large absorption cross-section for near infrared light [12][13][14].…”

Gd2O3:Er3+@Gd2O3:Yb3+ core-shell nanofibers with cubic phase were successfully fabricated by electrospinning method. The structural, morphological properties were investigated by X-Ray diffraction, scanning electron microscopy. Under 980 nm excitation, the upconversion photoluminescence in visible light exhibits strong red emitting band with obvious splitting peaks resulted from stark splitting of energy level. The visible emissions are sensitive to temperature in the range of 303-543 K. The red emission displays quenching with elevation of temperature. The activation energy for thermal quenching is equal to 0.1408 eV. The temperature dependent multi-peaks of red emission were systematically investigated. Based on valley and peak ratio of I680.31nm/ I683.03nm in upconversion emission spectra, temperature sensing with constant absolute sensitivity was achieved. These results suggest Gd2O3:Er3+@Gd2O3:Yb3+ nanofibers are promising candidates for luminescence thermometry, which may provide their application values in both scientific research and industry.
