Abstract

Lanthanide ion-doped up-conversion yttrium oxyfluoride (YOF) materials have wide applications in lighting displays, biological imaging, anticounterfeiting, and more. Traditional wet chemical methods used to prepare YOF are time-consuming and have low reproducibility. Controllable and rapid synthesis of YOF micro- or nanoparticles remains a challenge for advancing their applications. In this work, Eu³⁺ and Yb³⁺ co-doped YOF nanoparticles were synthesized using a microwave-assisted method. The particles exhibited excellent up-conversion photoluminescence properties when excited with a 980 nm laser. The calcination temperature and doping concentration of rare earth elements significantly affect the emission color and intensity, and white color emission can be achieved using a single emitter by tuning the doped ion concentration.

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.
