UVB Persistent Luminescence of CaF<sub>2</sub>:Gd<sup>3+</sup> for Radiation Labeling and Tracing (Advanced Optical Materials 31/2024)
Ultraviolet-B Persistent Luminescence of CaF2:Gd3+ After exposure to X-ray, CaF2:Gd3+ continued to emit ultraviolet-B luminescence peaking at 313 nm, corresponding to the 6P7/2 → 8S7/2 transition of Gd3+. By X-ray photoelectron spectroscopy measurements, the valence variation model was excluded to explain the persistent luminescence of CaF2:Gd3+. Potential applications including static labeling and dynamic tracking were demonstrated depending on such ultraviolet-B persistent luminescence.
