Abstract

Bi3+/Ln3+:YVO4 nanocrystals with a mean size of 6 nm are prepared through a mixed solvothermal route. With Bi3+ doping, the excitation band corresponding to the Ln3+ emission is shifted from 280 nm to 345 nm, owing to the occurrence of Bi3+ → V5+ metal–metal charge transfer and the subsequent energy transfer to Ln3+ ions. Under near-ultraviolet excitation, the emission color of Bi3+/Ln3+:YVO4 nanophosphors can be easily tuned by changing the Ln3+ ions.

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.
