A series of Dy3+,Tb3+ and Eu3+ singly, doubly or triply doped BaGdF5 phosphors were synthesized by a one-step hydrothermal method with L-arginine, and their energy transfer, migrations and multicolored luminescence properties were investigated in detail. The as-prepared Dy3+,Tb3+ or Eu3+ doped samples showed strong blue, green and red emission, respectively. Different hues of green and red light were obtained by co-doped Dy3+,Tb3+ and Tb3+,Eu3+ in the BaGdF5 host, respectively. More significantly, in the Dy3+,Tb3+,Eu3+ tri-doped BaGdF5 phosphors, colors changed from yellow green to orange red by adjusting the doping concentration of Eu3+. Energy migrations from Dy3+ to Tb3+ and from Tb3+ to Eu3+ are reported in detail. Furthermore, the obtained samples exhibit paramagnetic properties at room temperature and low temperature. It is obvious that these Dy3+, Tb3+, Eu3+ singly or doubly or triply doped BaGdF5 nanomaterials with tunable multicolored luminescence properties may have potential applications in the fields of full-color displays, biological labels and bio-separation.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
