Abstract: Quantum dot–polymer composites have the advantages of high luminescent quantum yield (PLQY), narrow emission half-peak full width (FWHM), and tunable spectra, broad application prospects in display lighting fields. Research on dots embedded polymer films plates has made great progress both synthesis technology optical properties. However, due to shortcomings dots, such as cadmium selenide (CdSe), indium phosphide (InP), lead halide perovskite (LHP), poor water, oxygen, light stability, incapacity for large-scale synthesis, their practical is still restricted. Various polymers, methyl methacrylate (PMMA), polyethylene terephthalate (PET), polystyrene (PS), polyvinylidene fluoride (PVDF), polypropylene (PP), etc., are widely used packaging dot materials because plasticity, simple curing, chemical good compatibility with materials. This paper focuses development field backlight displays, summarizes expounds strategies, advantages, disadvantages different materials, provides inspiration optimization promotes wide-color-gamut display.

Abstract A significant class of semiconductor nanostructures, colloidal quantum dots (CQDs), which exhibit narrow emission spectrum and tunable frequency, are utilized for numerous flexible wearable applications including state‐of‐the‐art display, biological sensing, showcasing great prospects in physiological measurement, health monitoring, rehabilitation. Interestingly, synthesizing these particles using methods such as hot injection colloids can directly tune their optical properties wavelengths by controlling sizes, greatly contributes to materials production simplicity scalability. Importantly, from a device perspective, due the advantages solution‐processed synthesis, patterning inkjet printing, CQDs be combined with soft polymeric substrates, or hierarchical structures facile manner, offering extraordinary flexibility portability. As optoelectronic devices, CQD function photoresistors, phototransistors, through other mechanisms convert light between forms energy, enabling highly sensitive detection applications. In this Review, synthetic approaches summarized CQDs, fabrication techniques, mechanisms, application scenarios. Furthermore, challenges associated technologies, stability cost‐efficiency discussed, present outlook on future trends devices multi‐functional integration, constituent component devices.

Abstract Optoelectronic biointerfaces have emerged as a promising platform for controlling the nervous system at cellular, tissue, and organ levels with potential clinical applications via transduction of light energy to ionic currents. To improve charge injection, supercapacitor materials like IrO x , TiN, PEDOT been incorporated an additional layer on photodiodes electrode–electrolyte interfaces. Here, bioelectronic design is demonstrated where AgBiS 2 quantum dots (QDs) serve photoabsorption material, hole transport medium, pseudocapacitive interface. The power‐law behavior anodic cathodic peaks suggests that diffusion‐controlled capacitive processes contribute storage mechanism. Furthermore, 3D Bode capacitance maps phase angle responses indicate high 3.3 mF cm⁻ half‐wave (0.044 V vs Ag/AgCl) in artificial cerebrospinal fluid (aCSF). For efficient electrical stimulation, QDs are embedded onto ZnO nanowires (NWs) photovoltaic device architecture, which produces twice photocurrent (1.9 ± 0.3 mA ) nearly three times injection (29 2.3 µC compared planar devices without NWs. Moreover, photostimulation hippocampal neurons inducing significant oxidative stress. This study demonstrates unconventional optoelectronic nanocrystals.

Abstract A facile synthesis and application of photon upconversion (UC) probes, CuInS₂/ZnS quantum dots (nCIS QDs) is presented, which exhibits near‐infrared (NIR) spectral emission. The nCIS QDs are synthesized via a template‐assisted cation‐exchange reaction during heating process, resulting in NIR‐I emission with large Stokes shift (≈650 meV) high photoluminescence yield (PLQY, ≈0.95). This behavior attributed to mechanism that produces wurtzite crystal structure deep defect states, leading relatively long fluorescence lifetime (≈5 µs ). confinement effect allows for the light at different wavelengths by adjusting size nanocrystals. Moreover, their states facilitate UC self‐trapping triplet‐triplet annihilation mechanism. promising potential explored imaging, demonstrating high‐contrast NIR imaging under IR vision modules, even presence interference layers. It suggests applications surgical guidance future biomedical imaging.
