Bismuth (Bi) metallic material is one of the most widely used heavy metals because of its low cost, excellent light conversion efficiency, and high X-ray attenuation coefficient. However, large-scale synthesis of highly processable and oxidation-resistant Bi nanoparticles remains challenging. Based on the above concerns, we report a facile, scalable, polyol-mediated synthesis of high-quality Bi nanoparticles using citrate as a capping agent and polyvinylpyrrolidone (PVP) as a dispersant. The presence of citrate and PVP improved Bi nanoparticle's oxidation resistance and processability. These nanoparticles can maintain excellent oxidation resistance in an ambient atmosphere for more than 120 days and form high-quality suspensions in various commonly used solvents. Moreover, large-scale and rapid synthesis of the nanoparticles was achieved by simply using the green reagent stannous citrate [tin (II) citrate] as a reducing agent. These properties make them promising as complementary conductive fillers in electrically conductive adhesives (ECAs). The Bi nanoparticles could be effectively combined with silver flakes in epoxy resins to enhance the conductivity of ECAs significantly. With the addition of only 5 wt % Bi nanoparticles, the resistivity of ECAs could be reduced to 1/3000 of that of ECAs with the same silver content, showing great promise in next-generation ECA products.

Bismuth oxyiodides have been gradually regarded as a kind of promising optoelectronic material, owing to their various merits, like relatively narrow and tunable band gap, high anisotropic crystal structure, and less toxicity. However, the investigation of bismuth oxyiodide-based photodetectors is still in the early stage, which might be attributed to the immature film deposition techniques in controlling their phase composition and surface morphology. In this work, high-quality Bi4O5I2 thin films were synthesized for the first time by a facile solution-based deposition technique, mist chemical vapor deposition. The synthesized Bi4O5I2 thin films were composed of vertically aligned nanoplatelets. With the increasing synthesis temperatures, the size of the nanoplates and film thickness increased. The iodide content was influenced by the synthesis temperatures such that the I:Bi molar ratio for the Bi4O5I2 thin films at intermediate temperature was close to 50%. The Bi4O5I2 photoelectrochemical (PEC)-type photodetectors were fabricated and exhibited excellent photodetection performance with the highest responsivity of 19.4 mA/W and detectivity of 3.54 × 1010 Jones. In addition, Bi4O5I2 PEC-type photodetectors presented good long-term stability in that the photocurrent density only decreased by around 25% after 6 h, which was superior to most 2D material-based PEC-type photodetectors. These results demonstrated that the Bi4O5I2 thin film has great potential in high-performance optoelectronic devices.

Broadband photodetectors (PDs) have garnered significant attention due to their ability to detect optical signals across a wide wavelength range, with applications spanning military reconnaissance, environmental monitoring, and medical imaging. However, existing broadband detectors face several practical challenges, including limited detection range, uneven photoresponse, and difficult to distinguish multispectral signals. To address these limitations, this study presents a self‐powered ultra‐wide PD based on the Bi2Se3/AlInAsSb heterojunction. The device can detect signals across a wide wavelength range from 250 nm to 1900 nm, exhibiting outstanding optoelectronic performance with a maximum responsivity of 0.5 A W−1, a detectivity of 4.2 × 1012 Jones, a switching ratio of 1.1 × 104, and an external quantum efficiency of 71.4%. Furthermore, the detector achieves a detectivity greater than 1010 Jones across the entire broadband range, significantly improving photoresponse uniformity. Notably, due to the differential band alignment of the two materials across spectral ranges, this detector exhibits a photocurrent polarity reversal in the 650–680 nm range. Leveraging its broadband and bipolar characteristics, this PD successfully enables secure information encryption in communication systems. This study significantly advances broadband PD technology, enhancing its practical uses and introducing innovative solutions for secure communications, thus strengthening communication security and confidentiality.
