要旨

Eu3+-doped transparent glass ceramics containing In2O3 nano-crystals were prepared by melt quenching and subsequent heating. X-ray diffraction analysis, transmission electron microscope observation, and photoluminescence excitation spectra demonstrated that In2O3 nano-particles sized 3–6 nm homogenously distributed among the glass matrix. Under excitation of these nano-particles, Eu3+ luminescence was found greatly enhanced due to the energy transfer from the oxygen-vacancy-related defects of In2O3 to Eu3+ ions. The Eu3+ content dependent energy transfer efficiency was evaluated, and the value reached 67% for 1 mol% Eu3+ doped glass ceramics. Low temperature emission spectra demonstrated that the Eu3+ ions of the glass ceramic locate mainly in the glass matrix.

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.
