Pr3+-doped RbCaF3: a new X-ray-induced UVC persistent phosphor
The development of persistent ultraviolet-emitting phosphors is advancing rapidly because of their promising applications in alternative cancer treatments. In this work, we developed a novel Pr3+-doped RbCaF3 phosphor exhibiting intense long-persistent luminescence in the 220–340 nm range, sustained for more than an hour after just 15 min of X-ray irradiation. The 5d-4f luminescence of Pr3+ ions is primarily excited by electron-hole pairs generated during X-ray absorption, as well as by electrons released from traps. The emission and excitation properties of RbCaF3:Pr3+ crystallites were further investigated using synchrotron radiation, revealing the simultaneous occurrence of intra-configurational 4f2→4f2 and inter-configurational 4f5d → 4f2 radiative transitions upon 4f5d state excitation. This work highlights the potential of Pr3+-doped RbCaF3 phosphor for innovative applications in ultraviolet photonics and cancer therapy.
期刊介绍:
The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid.
We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
