Summary: The study investigates the sulfurization of InP(111) surfaces using vaporized Sb2S3 and Bi2S3, exploring the effects of temperature on the substitution of atoms and epitaxial growth orientation. It reveals that the coverage with Sb and Bi changes the surface free energy, leading to alterations in growth orientation. Additionally, the deposition of polycrystalline Sb2S3 films is facilitated by the thermally activated sticking of Sb2S3 species to the InP surfaces.

Summary: This study reports the fabrication of cadmium-doped indium sulfide thin films using a low-cost spray pyrolysis process for photo-sensing applications. The impact of different cadmium concentrations on the structure, morphology, optical properties, and photo-sensing capabilities of the thin films was examined. The results showed that the 4% cadmium-doped sample exhibited excellent absorption in the visible and ultraviolet regions, and had high performance in terms of light current, responsivity, and detectivity. Therefore, this Cd-doped indium sulfide thin film sample may be well-suited for photodetector applications.

Summary: This study investigates the surface enhanced fluorescence (SEF) of fluorescein (FL) by silver nanoparticles (Ag NPs) and its implications for human cell imaging. The Ag NPs were characterized and their interaction with FL and a cationic surfactant, CTAB, was studied. The distance-dependent fluorescence enhancement of FL by Ag NPs was theoretically correlated. The study confirms that the Ag NP/FL mixed system can produce a brighter and more intense fluorescence image in human lung fibroblast cells, potentially offering a higher resolution and more contrast for cell imaging.

Summary: The experiment showed that deep point defect levels in GaN, AlN, and AlGaN remain constant with respect to the vacuum level, serving as invariant internal energy references. This allows for a convenient way to assess band shifts and impurity levels as temperature changes through photoluminescence. In AlGaN, it was found that the band shift is primarily in the valence band, with a relatively small change in the conduction band edge.

Summary: This study reveals the pressure-induced emission (PIE) mechanism of self-trapping excitons (STEs) in low-dimensional halide perovskites by investigating a 2D layered double perovskite material. The results show that pressure can transform dark-state STEs into bright-state STEs, resulting in a strong broadband Stokes-shifted emission. The theoretical analysis further explains that the suppressed lattice distortion and enhanced electronic dimensionality in the excited-state play crucial roles in stabilizing the bright-state STEs.

Summary: Different from conventional piezochromic materials, our designed molecule exhibits sensitive and tunable luminescence in response to hydrostatic pressure. The molecule possesses dual-emission and bidirectional shifting characteristics. Experimental studies reveal that the dual-emission behavior is attributed to intramolecular charge transfer and intermolecular excimer. The color change of the molecule from sky-blue to green to deep-blue is a result of intramolecular and intermolecular energy-transfer interactions.

Summary: Efficient warm white light emission is sought after in single-component materials for light-emitting applications. This study observed an unusual pressure-induced warm white emission enhancement in 2D perovskite (2meptH(2))PbCl4, accompanied by a significant increase in photoluminescence quantum yield. The collapse of the crystal structure triggered by octahedral distortions and the evolution of organic cations led to the emission enhancement, and further collapse promoted the formation of self-trapped excitons and suppressed nonradiative transitions, resulting in continuous photoluminescence enhancement under pressure.

Summary: The properties of mechanoresponsive materials are influenced by intermolecular interaction, which can be modulated using anisotropic grinding and hydrostatic high-pressure compression. Applying high pressure to DPH results in an increased emission and red-shifted piezochromism due to reduced molecular symmetry and pi-pi interactions. By controlling intermolecular interactions, NLC mechanical response can be achieved, while grinding destroys these interactions leading to a blue-shifted luminescence. The evolution of intermolecular interactions has important implications for developing new fluorescence materials and structural materials.

Summary: High sensitivity and multi-mode optical pressure sensing were achieved for the first time by co-doping Eu2+ and Mn2+ ions in the Lu2Mg2Al2Si2O12 (LMAS) host. The co-doping strategy proposed in this research significantly improves the pressure response range of the phosphors, and the decay degree of the overall integral intensity and the fluorescence intensity ratio (FIR) were first proposed to be used for pressure sensing. Therefore, multi-mode optical pressure sensing can be realized with the use of the LMAS:Eu2+,Mn2+ phosphor.

Summary: In this study, we investigated the optical and structural responses of a one-dimensional metal halide (HMTA)(3)Pb2Br7 under pressure. We found that applying mild pressure (<0.6 GPa) resulted in enhanced broadband emission and prolonged carrier lifetime. Additionally, the band gap narrowed with pressure due to enhanced orbital coupling between the metal and halogen. Our high-pressure studies not only reveal the regulation mechanism of self-trapped exciton (STE) emission in one-dimensional metal halides, but also highlight the potential of pressure treatment as a powerful strategy to tune the emission of white-light materials.

Summary: The wide application of excimer materials in the OLED field is mainly driven by the regulation of their stacking structure. This study designed three anthracene derivative molecules with sterically hindered substituents and prepared crystals with different aggregating structures to investigate the relationship between their structures and properties. The study found that under high pressures, these anthracene groups exhibit enhanced fluorescence during the formation of excimers, while the ones that have already formed excimers under ambient conditions show a wider red-shift range. The piezochromic fluorescence behavior observed indicates that regulating the aggregation mode of anthracene groups can meet different application requirements and guide the expansion of excimer materials' usage.

Summary: The pressure-dependent luminescence behavior of purely organic compounds is an important topic in the field of stimulus-responsive smart materials. This study filled in the gap regarding pressure-dependent room-temperature phosphorescence (RTP) of purely organic compounds by investigating the model molecule selenanthrene (SeAN) with a folded geometry. It discovered a unique phenomenon of pressure-induced RTP enhancement in an SeAN crystal, along with an underlying mechanism involving folding-induced spin-orbit coupling enhancement. In addition, pressure-induced RTP enhancement was observed in an analog of SeAN, which exhibited white-light emission.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
