| 英文摘要 | A novel upconversion (UC) luminescent phosphor Bi3.84W0.16O6.24:Tm3+, Yb3+ was synthesized via co-precipitation method. Distinct visible blue, red, and near-infrared light and weak purple and ultraviolet light UC emissions were all detected under 980 nm excitation in Tm3+-Yb3+-codoped Bi3.84W0.16O6.24 phosphor. Addition of Li+ or Mg2+ ions in Tm3+ -and Yb3+-codoped Bi3.84W0.16O6.24 phosphors further enhanced the blue and red emission intensities. The slope values of the log-log graph of pump power and emission intensity decreased to 1 for the blue emission because of the saturation effect, which was investigated in detail by theoretical and experiment analyses. Optical temperature sensing performances were evaluated in the NIR region from 313 K to 573 K based on the H-3(4(1)) and H-3(4(2)) of Tm3+ ions as thermal coupled energy levels. The corresponding optimum sensitivities were 0.000676, 0.00103, and 0.000696 K-1 at 323 K for free, Li+ ion-, and Mg2+ ion-codoped Bi3.84W0.16O6.24: Tm3+, Yb3+ phosphors, respectively. The introduction of alkali metals (Li) or alkaline earth metals (Mg) also enhanced the temperature sensitivity of the Bi3.84W0.16O6.24:Tm3+, Yb3+ phosphors in the NIR region. |
