要旨

The emission spectra of the tripositive lanthanide ion Eu3+ have often been employed to probe its environment in the solid state, and the intensity ratio of magnetic dipole (5D0 → 7F1) and forced electric dipole (5D0 → 7F2) transitions has been used to estimate the “degree of asymmetry” of a crystal site. From the site-selective, low temperature emission spectra of Eu3+ doped into a glass, a new empirical relation has been found between the width of spectral features and the relative intensity of the 5D0 → 7F0 zero phonon line. In order to explain the observations from experiments with excitation at different wavelengths, a generic quantitative relation has been developed from basic theory and validated from our experimental results. This work gives a deeper insight and understanding of the spectral characteristics of Eu3+ electronic spectra in the visible region.

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.
