要旨

CdTe nanocrystal/polyaniline composite films as well as films of closely packed CdTe nanocrystals were used to fabricate light-emitting devices with low turn-on voltages [∽2.5 V for a device with a Mg cathode and an indium tin oxide (ITO) anode]. In principle, the emitted colour is tunable from green to red, depending on the size of the nanocrystals. The use of the particle loaded polyaniline film as the light-emitting layer results in a considerable enhancement of the quantum efficiency in comparison with the polymer-free device with closely packed CdTe nanocrystals. The light-emitting devices are found to work more efficiently in a pulsed mode than under continuous operation.

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.
