Quantum dots (QDs) are nanosized semiconductor crystals with unique chemical and physical properties, enabling them to emit bright, photobleaching-resistant light. They classified into three categories: core type QDs, core-shell alloyed QDs. Core-type QDs composed of a single substance, while have surrounded by shell another material. Alloyed manufactured using high-temperature or wet-chemical processes, silicon-based display unusual optical electrical features due quantum confinement forces. exceptional optoelectronic capabilities, producing photoluminescence yields up 90%. useful for various applications, including optoelectronics photocatalysis. There main types QDs: colloidal, magnetic, fluorescent. Colloidal synthesis is widely used technique creating offering applications in visible near-infrared wavelengths. Magnetic magnetic characteristics can be synthesized methods. Fluorescent high fluorescence resistant photobleaching, making imaging, sensing, therapies. being developed enhance biological imaging capabilities increasing cellular uptake, reducing toxicity, enhancing stability. intracellular deep tissue single-molecule tracking, super-resolution targeting ligands, selective mitochondria, pH-responsive fluorescence, responding specific signals, self-illuminating systems.

Metal nanoparticles or periodic metal nanostructures exhibit localized surface plasmon resonance (LSPR) effects, widely employed in photovoltaic devices to enhance the light absorption. In this study, we used a double-metal-cladding waveguide (DMCW) structure fabricate hexagonal on front side of indium tin oxide (ITO) glass, positioned away from incident direction. We then prepared perovskite solar cells under various reaction conditions. The analysis results indicate that nanostructure chip excites near-field coupling, generating strong fields, and enhances absorption through LSPR effect. (PSCs) with structures exhibited significant increase short-circuit current density (J SC ) fill factor (FF), accompanied by decrease dark current, indicating improved characteristics cells. Altering evaporative deposition time silver film concentration solution led 12.79% power conversion efficiency (PCE) PSCs.

Abstract Quantum dots (QDs) are promising semiconducting luminous nanocrystals with superior optoelectronic characteristics. Unfortunately, these fragile when exposed to humid environment. Oxygen and moisture molecules could erode QDs’ structure degrade their ability, which severely hinders the wide application of QDs in devices. Therefore, it is significantly important resist oxygen/moisture permeation packaging converted In this review, we briefly introduce oxygen/moisture-induced degradation mechanism then theories. Subsequently, review some strategies for resisting from a perspective, analyze them Finally, outline future directions developing efficient resistance solutions

Abstract Cu:CsPbCl x Br 3‐x quantum dots (QDs) with different Cu‐to‐Pb molar ratios were synthesized via a solvent‐based thermal synthesis method, and highly stable blue‐light PCL@Cu:CsPbCl composite fibers (CFs) prepared by electrohydrodynamic (EHD) technology. The photoluminescence (PL) properties of these Cu 2+ ‐doped QDs the stability polymer encapsulation investigated in this study. results showed that increasing concentration, CsPbCl 1.5 maintained their initial cubic crystal structure. doping ions effectively eliminated surface defects QDs, facilitating excitonic recombination through radiative pathways. PL yield (PLQY) increased to 85%. In addition, fiber method improved After 3 days water, fluorescence intensity still remains at 90%. Based on results, it is believed have promising applications optoelectronic devices future.
