Research shows that the three-oscillator model accurately describes the optical constants of CsPbBr3, and time-resolved photoluminescence can accurately predict the electric field intensity distribution and cavity length.

Summary: Chalcogenide films of Ge25Se75 were prepared by thermal evaporation, exhibiting polycrystalline nature after annealing at 340 degrees C. The high transmittance at 1000 nm suggests their potential as color filters. With an increase in annealing temperature, the optical band gap energy was found to increase, demonstrating potential for optical applications.

Summary: This article investigates the effects of post-thermal annealing treatment on the properties of tin nitride thin films. With increasing annealing temperatures, changes in the film structure and crystallinity occur, along with the release of nitrogen leading to variations in film properties. Changes in optoelectronic properties are closely related to alterations in crystallinity and stoichiometry.

Summary: In this study, Mn doped CeO2 thin films were deposited and their crystal structure, surface morphology, and optical properties were investigated using X-ray diffraction, Raman analysis, atomic force microscopy, and spectroscopic ellipsometry. The results showed that the crystal structure, surface morphology, and optical properties of the films were influenced by the Mn doped content, and the values of n and Eg increased linearly with increasing Mn doped content.

Summary: The study showed that thermal annealing has a significant impact on the structural and optical properties of BixIn35-xSe65 thin films, leading to the development of crystalline phases at 450 degrees C. The linear and nonlinear characteristics of the films increased greatly after annealing, with the decrease in optical bandgaps attributed to the formation of surface dangling bonds near crystallite sites.

Summary: This paper investigates the structural, morphological, optical, and electrical conduction properties of 2D WSe2 thin films deposited by electron beam evaporation at room temperature. The study finds that the thickness of the films affects their nanostructure, optical constants, and energy bandgap. Additionally, the thin WSe2 films demonstrate wide absorption and a closely matched energy gap, making them promising candidates for photovoltaic applications.

Summary: In this study, the robustness of optical constants and optical band gap determination of three different materials is compared using a combination of spectroscopic ellipsometry and energy loss signal of X-ray photoelectron spectroscopy. The hybridization of these two techniques provides a new robust method for determining the band gap of the studied materials and other optical properties over a wide energy range.

Summary: The temperature-dependent optical properties of UO2 films were determined using spectroscopic ellipsometry. Thickness-controllable UO2 thin films were prepared by spin-coating nano-UO2 inks on substrates. Monodisperse UO2 nanoparticles with an average size of 6 nm were successfully synthesized, and the structural characterization of the UO2 films was reported. The study also investigated the optical properties of UO2 films and contributed to the understanding and database of UO2's optical properties.

Summary: The study investigates the diffusion of Zn into CdS films using vacuum annealing, where it is found that increased Zn content leads to decreased lattice constants, increased grain size, and bandgap. Vacuum annealed films show a significant increase in transmittance, which may enhance the efficiency of photovoltaic cells and optoelectronic devices.

Summary: Single-phase Ce0.97Co0.03O2 films are successfully deposited on Si(100) by radio-frequency magnetron sputtering, and the effects of substrate temperature on their structural and optical properties are investigated. The results show that the crystallite size increases and the surface roughness increases with increasing substrate temperature. The values of the optical constants increase while the value of E(g) decreases with increasing substrate temperature.

Summary: The method of spectroscopic ellipsometry is used to investigate complex periodic nanomaterials with intense resonant structural color. A multilayer optical quasi-model is developed to understand the correlation between ellipsometric parameters and shear-induced crystallinity. These approaches provide reliable means for in-line tracking of sample quality in large scale processing and applications of such materials.

Summary: Epitaxial thin films may not always experience compressive or tensile strain from the nearest layer with a smaller or larger lattice constant, respectively, if the interface is anisotropic in the plane. A novel strain mechanism, taking the pre-strain state into account as a key factor rather than just considering lattice mismatch, is proposed. This anomalous strain model could be significant for various multifunctional devices based on strain coupling.

The use of MDSplus for real-time segmented data storage and integration of a GUI written in Python were essential components of the system. The subsystem was successfully applied for real-time feedback control in EAST and played a critical role in divertor physics experiments during the 2021 EAST operation campaign.

Summary: HL-2M is a medium-sized tokamak constructed by the Southwestern Institute of Physics (SWIP) in China. A new plasma control system (PCS) based on the software framework of DIII-D PCS for HL-2M has been proposed to replace the original loose system. The new PCS hardware consists of three computer nodes and peripheral equipment, with data acquisition completed by a standing server and a reflective memory network. The software architecture of DIII-D PCS is generally retained, but with added interfaces to adapt to the existing system. The upgraded Linux operating system enables better performance for real-time tasks. Preliminary verification through simulation shows that the new PCS can output control commands as expected.
