“…For example, the green phosphor Ca 6 La 4 (SiO 4 ) 2 (PO 4 ) 4 O 2 :0.01Eu 2+ prepared by Xia [4], its emission peak of 500 nm was emitted from the 4f and 6h positions occupied by Eu 2+ , and the quantum efficiency was 57.73%. Besides, Tian [5] prepared fluorescent powder Ca 9 Sr(PO 4 ) 6 Cl 2 :Ce 3+ ,Tb 3+ by high temperature solid phase method. Based on the effective energy transfer between Ce 3+ and Tb 3+ , the green emission peak of Tb 3+ at 541nm was significantly increased, and the energy transfer efficiency of Ce 3+ →Tb 3+ was up to 76%.…”

A series of Ce 3+ /Tb 3+ singly doped and Ce 3+ , Tb 3+ co-doped Ca 3 GdNa(PO 4 ) 3 F phosphors were synthesized via high temperature solid-state reaction in a reductive atmosphere. The crystal, luminescence properties, energy transfer mechanism and thermal stability of the samples were investigated in detail. The Ce 3+ doped phosphors can be excited in the range from 250 to 330 nm. The Ce 3+ ,Tb 3+ co-doped phosphors exhibit characteristic emission of Ce 3+ and Tb 3+ simultaneously under the excitation of 301 nm. In addition, the energy transfer efficiency from Ce 3+ to Tb 3+ reaches as high as 78.6% when the doping amount of Tb 3+ is 0.20. The mechanism of energy transfer between Ce 3+ and Tb 3+ ions is demonstrated to be a dipole−dipole interaction. The luminescence characteristics show that this phosphor can be a platform for modeling a new phosphor and application in the solid-state lighting field.

Lanthanide (Ln3+) based luminescent materials, with their distinctive emission spectra, offer opportunities to develop novel coding patterns for various applications, including Tracer Based Sorting (TBS). TBS uses trace amounts of inorganic phosphors and is a promising method for sorting plastics based on criteria beyond plastic type. This study investigates the synergistic effect of co‐doping with Ce3+ to enhance Er3+ luminescence at ≈1550 nm (with a maximum photoluminescence quantum yield (PLQY) of 5.7%) while significantly reducing Yb3+ luminescence at ≈1000 nm. The underlying mechanisms of these properties are analyzed using absolute PLQY measurements in an integrating sphere, luminescence decay studies, and X‐ray photoelectron spectroscopy. Hyperspectral shortwave infrared imaging reveals an extended range of unique tracer combinations based on ratiometric intensity measurements, particularly when the Yb3+/Er3+/Ce3+ tracers are mixed with a single‐doped Yb3+ tracer, compared to simple mixtures of Ce3+‐free Yb3+/Er3+ and Yb3+ tracers. Therefore, the use of the tri‐doped Yb3+/Er3+/Ce3+ Gd2O2S tracer increases the diversity of available luminescent tracers that may be of potential interest in the identification and sorting of plastic waste using the TBS process.
