“…Finally, the standard deviation was calculated for each sample by using Equation (1):

where σ donates the standard deviation, n is the number of samples or thickness, x is the individual thickness values, and the

is the mean or the average value due to the non-uniformity or unevenness with cracks and voids of the FESEM surface morphologies. The observed thickness fluctuation due to the nonuniform distributions of the NRs on the glass substrate was attributed to the LA concentration-dependent structural and morphological alterations that occurred during the deposition at a high bath temperature for an extended period [ 18 , 19 , 20 ]. The average thickness of the ZONRs-TFs obtained with 2 and 3 wt.% of BN was much lower than those achieved with LA and LN doping.…”

The fabrication of Nano-based shielding materials is an advancing research area in material sciences and nanotechnology. Although bulky lead-based products remain the primary choice for radiation protection, environmental disadvantages and high toxicity limit their potentials, necessitating less costly, compatible, eco-friendly, and light-weight alternatives. The theme of the presented investigation is to compare the ionization radiation shielding potentialities of the lead acetate (LA), lead nitrate (LN), and bismuth nitrate (BN)-doped zinc oxide nanorods-based thin films (ZONRs-TFs) produced via the chemical bath deposition (CBD) technique. The impact of the selected materials’ doping content on morphological and structural properties of ZONRs-TF was investigated. The X-ray diffractometer (XRD) analyses of both undoped and doped TFs revealed the existence of hexagonal quartzite crystal structures. The composition analysis by energy dispersive (EDX) detected the corrected elemental compositions of the deposited films. Field emission scanning electronic microscope (FESEM) images of the TFs showed highly porous and irregular surface morphologies of the randomly aligned NRs with cracks and voids. The undoped and 2 wt.% BN-doped TFs showed the smallest and largest grain size of 10.44 nm and 38.98 nm, respectively. The linear attenuation coefficient (µ) values of all the optimally doped ZONRs-TFs measured against the X-ray photon irradiation disclosed their excrement shielding potency. The measured µ values of the ZONRs-TFs displayed the trend of 1 wt.% LA-doped TF > 1 wt.% LN-doped TF > 3 wt.% BN-doped TF > undoped TFs). The values of μ of the ZONRs-TFs can be customized by adjusting the doping contents, which in turn controls the thickness and morphology of the TFs. In short, the proposed new types of the LA-, LN- and BN-doped ZONRs-TFs may contribute towards the development of the prospective ionization radiation shielding materials.

“…23 There are still few reports concerning the synthesis of these oxyhalides as thin films because there are some difficulties, such as the incompatibility of the precursor salts or the need to use strong acids that limit the number of deposition techniques. In addition, the thin film materials are frequently obtained as a mixture of phases [24][25][26] that complicate the analysis of the contribution of each material. Nevertheless, for the degradation of pollutants in water, it is important to have the materials as thin films to easily recover the photocatalyst and avoid separation processes.…”

“…As for the thin film deposition method, many research articles have reported various synthesis techniques such as CVD [13], chemical bath deposition (CBD) [30], sol-gel method [31], spin coating [27] and dual-port ultrasonic spray pyrolysis technique [32], successive ionic layer adsorption and reaction (SILAR) process [10,[32][33][34][35] to produce BiOI thin films. To fabricate the BiOI solar cell at low cost in the future, all-solution process without using vacuum at low temperature is preferable.…”

This research demonstrates a complete solution prepared environment-friendly high-performance solid-state BiOI photovoltaic cell with high-short-circuit current for the first time. All the layers have been prepared at room temperature in the atmosphere without using the vacuum process. The photovoltaic properties are improved with employing both electron transport layer (ETL) and hole transport layer (HTL) and with increasing the cycle number of the SILAR process up to 30 cycles where the maximum short-circuit current density, J SC = 7.6 mA/cm 2 and the open-circuit voltage, V OC = 0.63 V, respectively. The ETL and HTL effects on the photovoltaic properties are discussed together with absorption spectrum and external quantum efficiency.
