We develop a rapid and spatially controlled formation method of a smooth polycrystalline SnO film preventing the transition to a more stable SnO phase. The phase and structural state of a SnO oxide film, which was formed by pulsed irradiation of a Nd:YAG laser on a tin plate in contact with air and distilled water, were studied. XRD, Raman spectra, and kinetics of the exciton PL under femtosecond excitation showed a more perfect textured structure and strong exciton emission of the SnO film obtained by the laser under the conditions of Sn contact with air. The obtained results indicate the applicability of the laser method for the formation of SnO layers, according to the given topology, which can be used for UV-emitting devices and photocatalysts.

Enhancing the performance of organic solar cells (OSCs) is essential for achieving sustainability in energy production. This study presents an innovative strategy that involves fine-tuning the thickness of the bulk heterojunction (BHJ) photoactive layer at the nanoscale to improve efficiency. The organic blend D18:L8-BO is utilized to capture a wide range of photons while addressing the challenge of minimizing optical losses from low-energy photons.

Stability testing protocols from the International Summit on Organic and Hybrid Solar Cell Stability (ISOS) are essential for standardizing studies on the photothermally operational stability of perovskite solar cells (PSCs). Under photothermal conditions, the migration of oxygen from SnO layer induces cationic dehydrogenation at the A-site of the perovskite, accelerating degradation to PbI. This leads to the formation of photoinduced I and Pb defects, significantly compromising long-term stability.

The chemical regulation of SnO to enhance the properties of the buried interface in perovskite films is extensively investigated, but the underpinning mechanisms remain insufficiently understood. In this study, a synergistic strategy for cation fixation and anion diffusion by incorporating (3-amino-3-carboxypropyl) dimethylsulfonium chloride (Vitamin U, V) into a SnO colloidal solution is proposed. The cationic end (─COOH, ─NH) of V effectively inhibits the aggregation of SnO particles and promotes electron extraction and transport via chemical interactions.

High-energy ionizing radiation brings serious challenges to medical professionals, and it demands efficient and lightweight shielding materials depending on high-Z elements and structural supporting matrices. Herein, we have integrated multiple high-Z elements and multilayer structures into composite films with interlayer scattering effects for constructing high-energy X-ray shielding clothes. A series of composite films containing different combinations of X-ray shielding particles (SnO, BaSO, and BiO) were prepared in tightly connected two layers with each layer consisting of corresponding hybrid polyacrylonitrile (PAN) fibers-reinforced hybrid thermoplastic polyurethane (TPU) coating.

The use of quantum sized SnO nanocrystals as the electron transportation layer (ETL) in quantum dot light-emitting diodes (QLEDs) has been demonstrated to be an effective method for improving device stability and eliminating the positive aging effect. However, compared to the commonly used 4,4'-bis(-carbazolyl)-1,1'-biphenyl (CBP) hole transportation layer (HTL), the quantum sized SnO nanocrystals usually possess a higher electron mobility and a higher conductivity, which results in the charge transport imbalance in QLEDs. Herein, In-doped SnO quantum-sized nanocrystals are synthesized by the ligand-assisted solvothermal method.
