We report the synthesis, crystal structure, IR, Raman and luminescence studies of four metal–organic frameworks of the following formulas: [CH3CH2NH3]Y1−x−yYbyErx(HCOO)4 (x = 1, y = 0; x = 0.2, y = 0.8; x = 0.02, y = 0.07) and [CH3CH2NH3]Y0.92Eu0.08(HCOO)4. All the compounds are isostructural and crystallize in a polar and non-centrosymmetric monoclinic system (P21 space group). They have been characterized by single crystal and powder X-ray diffraction methods as well as by vibrational spectroscopy (IR and Raman). The assignment of the external and internal modes has been discussed and presented. Furthermore, the optical properties of the Er3+ and Eu3+ ions have been assessed using diffuse absorption, excitation and emission spectra. The site symmetry of the Eu3+ ions has been analyzed using the emission spectrum and the luminescence decay of the red emission.

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.
