Summary: This article presents an effective method for fabricating nanostructured whispering-gallery-mode (WGM) lasers by drop-casting CdSe/CdS@Cd1-xZnxS core/buffer-shell@graded-shell nanoplatelets (NPLs) dispersion onto silica microspheres. The room-temperature NPLs-WGM microlasers exhibit a record-low lasing threshold and stable single-mode laser output. Additionally, the Vernier effect through evanescent field coupling further optimizes the laser output performance.

Summary: I-III-VI ternary quantum dots (QDs) have been proposed as non-toxic alternatives to II-VI QDs in optoelectronics and biotechnology. However, their application as optical gain media for microlasers is constrained by low neous emission (ASE) and lasing. In this study, passivated AIS QDs showed enhanced fluorescence efficiency and two-photon absorption cross section. ASE was achieved from AIS/ZnS core/shell QD films under both one- and two-photon pumping, with comparable thresholds to Cd-based QDs. A whispering-gallery-mode microlaser of the core/shell QDs was also demonstrated.

Summary: Organic-inorganic halide perovskites exhibit excellent properties in WGM cavities, but the performance of perovskite-based microlasers is limited by the fabrication of microcavities. Researchers have developed a reproducible method combining thermal co-evaporation and femtosecond laser direct writing to create FAPbI(3) polygon-shaped WGM microcavities, and systematically investigated the size- and shape-dependent WGM lasing performances. The results show that FAPbI(3) polygonal microcavities have great potential as promising WGM lasers for practical optoelectronic applications.

Summary: In this research, a novel all-optical tunable microlaser based on a polymer-coated microcavity embedded with a high-efficiency nanoheater is proposed. The large refractive index contrast between polymer and air allows for whispering gallery mode (WGM) resonances, enabling lasing from polymer microshells via total internal reflection. By using a Nd3+ heavily doped NaGdF4 nanocrystal (NC) as a nanoscale heat source, a maximum photothermal conversion efficiency of 82.9% is achieved under the continuous triggering of a 793 nm laser. The nanoheater, doped into the silica core by infrared laser ablation, enables the coated microcavity to maintain a high Q factor up to 1.6 x 106, and significant heat transfer is achieved through the absorption of the 793 nm trigger light by the nanoheater.

Summary: In this study, a solution-based growth method of InZnO/AlInZnO heterojunction channel layers was reported and implemented in high-performance thin-film transistors. It was found that the heterojunction transistors exhibited band-like electron transport and significantly higher current ON/OFF ratio and mobility values compared to single-layer IZO and AIZO devices. The improvement was attributed to the presence of confined free electrons at the sharp heterointerface induced by the large conduction band offset between IZO and AIZO. Further channel engineering allowed the achievement of high-performance heterojunction oxide TFTs with excellent stability and potential in next-generation printable electronics.

Summary: Passivating the defective surface of perovskite film using 1-adamantanamine hydrochloride (ATH) improves the stability and efficiency of perovskite solar cells (PSCs). The ATH-modified device shows a higher efficiency (23.45%) compared to the control device (21.53%). The defects are repaired, nonradiative recombination is suppressed, and interface stress is relieved by depositing ATH on the perovskite film, resulting in longer carrier lifetimes and enhanced VOC and FF of the PSCs. VOC and FF are increased from 1.159 V and 0.796 for the control device to 1.178 V and 0.826 for the ATH-modified device, respectively. During a stability measurement of over 1000 hours, the ATH-treated PSC exhibits improved moisture resistance, thermal persistence, and light stability.

Summary: This study investigates the control of crystallization kinetics and halide ion migration in CsPbIBr2 perovskite solar cells through the modulation of chlorobenzene antisolvent and bis(pentafluorophenyl)zinc additive. The addition of Zn(C6F5)2 significantly reduces phase segregation in CsPbIBr2 films, as observed from photoluminescence and absorption spectra. Furthermore, the modified CsPbIBr2 PSCs exhibit a power conversion efficiency of 12.57% with negligible hysteresis and increased stability. Under 1-m-deep water, the PCE of CsPbIBr2 PSCs reaches 14.18%. These findings provide insights into the development of phase-segregation-free CsPbIBr2 films and demonstrate the potential applications of CsPbIBr2 PSCs in underwater power systems.

Summary: Fully solution-processed oxide thin-film transistors (TFTs) have great potential in future printable electronics. In this study, the effects of bilayer gate dielectrics on the performance of solution-processed indium zinc oxide (IZO) TFTs were investigated. The optimized TFTs with ZrOx/AlOx gate dielectrics showed significantly improved carrier mobility and current on/off ratio due to the passivation effects of AlOx, which reduced the trap/defect states at the dielectric/channel interface. With a low operating voltage of 2 V, high mobility, low subthreshold swing, and high current on/off ratio, these devices have great potential in future low-cost, low-power printable electronics.

Summary: Perovskite solar cells (PSCs) are highly promising due to their high efficiency, low cost, and ease of fabrication. Flexible perovskite solar cells (FPSCs), specifically, are lightweight and bendable, making them suitable for wearable and portable electronics, space energy systems, and more. Inverted p-i-n FPSCs offer operational stability, reduced hysteresis effect, low-temperature fabrication, and potential for tandem devices. With PCEs reaching 21.76% and 24.7% for single-junction and tandem-inverted FPSCs respectively, commercial applications are highly anticipated. This review discusses the development of functional layers and technologies for accelerating the commercialization of inverted FPSCs, providing perspectives on their future development and commercialization.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
