The nanorods of bismuth sulfoiodide (BiSI) were synthesized at relatively low temperature (393 K) through a wet chemical method. The crystalline one-dimensional (1D) structure of the BiSI nanorods was confirmed using high resolution transmission microscopy (HRTEM). The morphology and chemical composition of the material were examined by applying scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), respectively. The average diameter of 126(3) nm and length of 1.9(1) µm of the BiSI nanorods were determined. X-ray diffraction (XRD) revealed that prepared material consists of a major orthorhombic BiSI phase (87%) and a minor amount of hexagonal Bi13S18I2 phase (13%) with no presence of other residual phases. The direct energy band gap of 1.67(1) eV was determined for BiSI film using diffuse reflectance spectroscopy (DRS). Two types of photodetectors were constructed from BiSI nanorods. The first one was traditional photoconductive device based on BiSI film on stiff glass substrate equipped with Au electrodes. An influence of light intensity on photocurrent response to monochromatic light (λ = 488 nm) illumination was studied at a constant bias voltage. The novel flexible photo-chargeable device was the second type of prepared photodetectors. It consisted of BiSI film and gel electrolyte layer sandwiched between polyethylene terephthalate (PET) substrates coated with indium tin oxide (ITO) electrodes. The flexible self-powered BiSI photodetector exhibited open-circuit photovoltage of 68 mV and short-circuit photocurrent density of 0.11 nA/cm2 under light illumination with intensity of 0.127 W/cm2. These results confirmed high potential of BiSI nanorods for use in self-powered photodetectors and photo-chargeable capacitors.

High-performance photodetection is becoming increasingly important for the advancement of technology. Very few materials are available that can respond to light across the ultraviolet to the infrared (IR) range. These materials are very much required for optoelectronic devices. Two-dimensional (2D) layered materials became relevant following the discovery of graphene. Transition-metal chalcogenides belong to the 2D layered material class, as well. The field of optoelectronic applications makes extensive use of them. The current study investigated the photodetector device by doping pure SnS nanoflakes with Fe, Mn, Mg, Pd, and W. These materials were used to create paper-based, flexible, biodegradable electronics through a solvent-free hand-print technique. The Mgdoped SnS photodetector has the highest photo response performance among the devices. With a specific detectivity value of 1.64 × 10 10 Jones and a responsivity value of 52 mA W −1 , the 7% Mg-doped SnS exhibits the best response among the different Mg doping. Extensive on−off cycles were used to assess the switching stability of the device, observing clear photo response and photoswitching behavior. The photoswitching curves of the device as created and the device after 8 months show an amazing degree of consistency, indicating the device's resilience in open-air environments. The device was bent repeatedly to test its twisting, foldability, and flexibility. It continuously displayed a definite photoswitching trend. Testing in a very basic and acidic environment verified the device's chemical stability, and its photo response and photoswitching functions remain functional. When the paperbased photodetector's thermal stability was examined at various temperatures, the findings demonstrated that the device continues to function normally and produce photocurrent. Considering how quickly technology is developing nowadays and how much waste is produced by electronics, switching to paper-based gadgets could help achieve sustainability goals.
