Summary: Doping and blending strategies are crucial for controlling excited states and energy levels in conjugated molecular systems. However, effective models and platforms to explore the effects of trapped doped centers on heterogeneous structures and photophysical processes are rarely proposed. In this study, a supramolecular N-B coordination was designed to investigate the impact of molecular doping on film energy levels and photoexcitation dynamics. The results showed that the coordination bond increased N atoms' binding energy and tuned the band-gap, resulting in a new fluorescent emission center with longer excitation and emission wavelengths. The blending films exhibited inconsistent fluorescent behaviors compared to solution due to intermolecular Forster resonance energy transfer. Additionally, the charge transfer state and changed dielectric constant caused a red-shift in the photoluminescence spectra with increased dopant ratio, enabling wide-tunable fluorescent color. The excited state behaviors of the compounds in blending system were further studied using transient absorption spectroscopy. It was found that supramolecular coordination blending effectively improved the photoluminescence quantum yield and conductivity of the films. This exploration in coordination mechanisms provides insights into doped semiconductors and facilitates the development of high-efficient fluorescent systems.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
