In this work, -NaLuF4:Yb, Er (NLF) nanocomposites (NCs) and -NLF NCs with diameter about ∼13 nm were fabricated by a high temperature decomposition reaction method. The effects of NLF structure on the enhanced red upconversion luminescence performance were investigated. Under 980 nm excitation from a laser diode, the -NLF emitted dominant red UC emission. Furthermore, the possible energy transfer mechanism was proposed on the basis of our experimental results.

In this work the effects of NaYF4:Yb, Er (NYE) structure on the enhanced red upconversion luminescence (UC) was investigated. -NYE nanocrystals (NCs) and -NYE NCs were fabricated by a high temperature decomposition reaction method. The prepared NCs were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and photoluminescence (PL) spectroscopy. The results show that the red UC luminescence of -NYE NCs is significantly enhanced compared with that of -NYE. Furthermore, a possible energy transfer mechanism was proposed on the basis of our experimental results.

The phosphors Sr3B2O6: Ce3+, Sr3B2O6: Tb3+ and Sr3B2O6: Ce3+, Tb3+ were synthesized by the solid-state reaction method at high temperature. For the phosphor Sr3B2O6: Ce3+, the lowest 5d levels, the emission and the Stokes shifts of Ce3+ in the host lattice were identified. In addition, its concentration quenching process was also studied. For the phosphor Sr3B2O6: Tb3+, the f-d transitions of Tb3+ in the host lattice were assigned and discussed. Moreover, the energy transfer phenomenon between Ce3+ and Tb3+ in Sr3B2O6: Ce3+, Tb3+ was discussed. The emission of Tb3+ is significantly enhanced due to energy transfer from Ce3+ to Tb3+ when Ce3+, Tb3+ dopants were used together in Sr3B2O6.
