Abstract

Both spectra of transient absorption (λmax = 390 nm) and luminescence (λmax = 590 nm) for the 4T1 state of Mn2+ in ZnS nanoparticles shift to long wavelengths by 40 nm and broaden by 1.7 times as the state becomes banded. The 4T1 band of capping Mn2+ in ZnS nanoparticles decays on the time scale of 0.35 μs, which is much shorter than either the decay time of the 4T1 state (2000 μs) for lattice-bound isolated Mn2+ or that (180 μs) for surface-bound isolated Mn2+ in ZnS nanoparticles.

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.
