“…Moreover, an obvious blue shift appeared in emission peaks of Mn 2+ ions with an increase in the temperature, as displayed in Figure c. This phenomenon might be attributable to thermally activated phonon-assisted transitions from lower excited states to higher states . From Figure g–i, in comparison with the PL intensity at 298 K, the integrated PL intensities of Eu 2+ in NCMP:0.01Eu 2+ , NCMP:0.01Eu 2+ ,0.11Tb 3+ , and NCMP:0.01Eu 2+ ,0.10Mn 2+ at 423 K can remain at about 59.74%, 56.04%, 70.56%, respectively.…”

Here, the crystal structure, phase analysis, site occupancy, and luminescence properties of NCMP:Eu2+,Tb3+,Mn2+ have been studied for the first time. Under 335 nm ultraviolet excitation, the NCMP:Eu2+ phosphors show narrow-band blue emission. In addition, we discuss the reason for a continuous red shift for the emission spectra of NCMP:xEu2+ by raising the x value. The efficient ET processes of Eu2+ → Tb3+ and Eu2+ → Mn2+ were investigated by the luminescence spectra and decay curves. The ET efficiencies reach 92.58% at y = 0.15 for NCMP:0.01Eu2+,yTb3+ and 99.85% at z = 0.15 for NCMP:0.01Eu2+,zMn2+ phosphors, respectively. The efficient energy transfer processes greatly improve the quantum efficiency, luminous intensity, and thermal stability. Bright green and red emissions can be realized through changing the related ratio of Eu2+, Tb3+, and Mn2+. In addition, the excellent performance of the prepared white LED lamps utilizing a 385 nm chip combined with our prepared NCMP:Eu2+,Tb3+/Mn2+ phosphors indicates that NCMP:0.01Eu2+,yTb3+ and NCMP:0.01Eu2+,zMn2+ phosphors can be potential green and red phosphors for white LEDs.

Various novel SrBi2Ta2O9:Tm3+ blue-emitting materials were achieved via solid-state synthesis. The structure and phase purity of prepared SrBi2Ta2O9:xTm3+ (x = 0.005-0.30 mol) were examined by X-ray powder diffraction. The surface morphology of SrBi2Ta2O9:0.01Tm3+ were studied by scanning electron microscopy. Photoluminescence properties were systematically explored under the monitoring emission (λem = 468 nm) and excitation (λex = 303 nm) spectra. The optimum mole ratio of as-synthesized phosphors was 0.01 mol. The concentration quenching mechanism in the SrBi2Ta2O9 host was due to electric multipole interaction. Particularly, the chromaticity coordinates (0.1334, 0.0474) of SrBi2Ta2O9:0.01Tm3+ are near to those of the commercial BaMgAl10O17:Eu2+. These results validated the SrBi2Ta2O9:Tm3+ phosphor can be utilized good blue-emitting candidate for W-LEDs.

As increasing demand for noncontact temperature sensing, the development of a high-performance optical thermometer probe is more and more urgent. In this work, an efficient dual-mode optical thermometry strategy based on the Pr 3+ /Dy 3+ energy transfer (ET) in some typical double-perovskite oxides is presented, which offers a promising way to design FIR/lifetime dual-mode optical thermometry with excellent temperature-measuring sensitivity and signal discrimination. According to this strategy, double-perovskite La 2 MgTiO 6 :Pr 3+ /Dy 3+ phosphors are successfully synthesized. On the basis of diverse thermal responses between Pr 3+ and Dy 3+ , the FIR of Pr 3+ to Dy 3+ (four FIR mode) in this material displays outstanding optical thermometry performance from 298 to 548 K. The maximum absolute and relative sensitivities (S a and S r ) of mode 1 are 0.09 and 2.357% K −1 , being better than the current optical temperature measurement materials. For the fluorescence lifetime mode, the S a-max and S r-max values reach 2.85 × s 10 −4 and 1.814% K −1 . Furthermore, the dual-mode optical thermometry mechanism was presented and studied. It also demonstrated excellent optical thermometry performance in the other Pr 3+ /Dy 3+ codoped double-perovskite oxides, such as LaMg 0.598 Nb 0.402 O 3 , NaLa(MoO 4 ) 2 , NaGd(MoO 4 ) 2 , and NaLa(WO 4 ) 2 , proving the universality of the presented strategy. This article presents an effective Pr 3+ /Dy 3+ ET pathway for developing new and highly sensitive FIR/lifetime dual-mode optical temperature sensing materials.
