“…The diffraction peaks identified at 2θ = 24.91°, 26.65°, 28.29°, 36.70°, 43.77°, and 62.73° angles correspond to the (100), (002), (101), (102), (110), and (104) planes, respectively, indicating a hexagonal phase structure of the thin films. Among these, the (102) and (110) orientations exhibit higher peak intensities, suggesting a preferred directional growth of particles along these planes due to their lower surface energy, a phenomenon that is in agreement with the existing literature [ 48 , 49 , 50 , 51 , 52 ]. This preferred orientation is attributed to the stacking sequence of close-packed Cd planes, with S atoms occupying tetrahedral interstitial sites, emphasizing the significance of these dominant orientations in the crystal growth process [ 53 ].…”

UV sensors hold significant promise for various applications in both military and civilian domains. However, achieving exceptional detectivity, responsivity, and rapid rise/decay times remains a notable challenge. In this study, we address this challenge by investigating the photodetection properties of CdS thin films and the influence of surface-deposited gold nanoparticles (AuNPs) on their performance. CdS thin films were produced using the pulsed laser deposition (PLD) technique on glass substrates, with CdS layers at a 100, 150, and 200 nm thickness. Extensive characterization was performed to evaluate the thin films’ structural, morphological, and optical properties. Photodetector devices based on CdS and AuNPs/CdS films were fabricated, and their performance parameters were evaluated under 365 nm light illumination. Our findings demonstrated that reducing CdS layer thickness enhanced performance concerning detectivity, responsivity, external quantum efficiency (EQE), and photocurrent gain. Furthermore, AuNP deposition on the surface of CdS films exhibited a substantial influence, especially on devices with thinner CdS layers. Among the configurations, AuNPs/CdS(100 nm) demonstrated the highest values in all evaluated parameters, including detectivity (1.1×1012 Jones), responsivity (13.86 A/W), EQE (47.2%), and photocurrent gain (9.2).

“…Hydrothermal synthesis presents some benefits: being very pure, with a regulated morphology; having a limited size distribution and comprising single crystals; having a high powder reaction rate; having good dispersion in liquid; and being almost pollution-free. What is more, the prepared powder is not conglomerated but is fine-grained, and it does not need high-tech equipment [67].…”

“…The solution temperature was kept at 60 • C and agitated for 3 s. The prepared combination was then placed in a Teflon-lined sealed stainless-steel autoclave and kept at 170 • C in the oven for 24 h. After slowly cooling down to RT, the final product was rinsed with dH 2 O multiple times, using an electrosonic machine; it was then lifted to dry at 50 to 60 • C overnight. Finally, it is possible to collect the yellow powder [67].…”

Cadmium sulfide nanoparticles (CdS NPs) have been employed in various fields of nanobiotechnology due to their proven biomedical properties. They are unique in their properties due to their size and shape, and they are popular in the area of biosensors, bioimaging, and antibacterial and anticancer applications. Most CdS NPs are generally synthesized through chemical, physical, or biological methods. Among these methods, biogenic synthesis has attracted more attention due to its high efficiency, environmental friendliness, and biocompatibility features. The green approach was found to be superior to other methods in terms of maintaining the structural characteristics needed for optimal biomedical applications. The size and coating components of CdS NPs play a crucial role in their biomedical activities, such as anticancer, antibacterial, bioimaging, and biosensing applications. CdS NPs have gained significant interest in bioimaging due to their desirable properties, including good dispersion, cell integrity preservation, and efficient light scattering. Despite these, further studies are necessary, particularly in vivo studies to reduce NPs’ toxicity. This review discusses the different methods of synthesis, how CdS NPs are characterized, and their applications in the biomedical field.

“…The formation of the Bi-2223 phase is particularly sensitive to a wide range of factorsSeveral factors can influence the synthesis of materials, such as sintering temperature, thermal processing duration, synthesis environment, precursor compositions, and the incorporation of different cations and anions through doping or replacement [27,28]. From what we can see, Ni2O3 micro Particles considerably enhanced the formation of Bi-2223 phase [5][6][7][8][9][10], suggesting that they may be somewhat compensating for Cu's slowing effect [21,26].…”

Partial compensation Ni2O3 nanoparticles have been considered in relation to their effects on the structure, electric, morphology, and composition of Bi-2223. X-ray diffraction was used to quantify structural characteristics, and the results showed that all of the crystals in the samples are orthorhombic, with the ratio at which the Bi-2223 phase develops increasing The constancy of the lattice along the c-axis was observed. The trend that has been observed suggests that there is a direct proportionality between the concentration of Ni2O3 and the magnitude of the increase. Suggestive of a high-temperature superconductor (Bi2Sr2-xYxCa2Cu3-yNiyO10+δ) composition, where y=0=0.03=0.12 Thanks to 3D AFM, the morphology of the surface has been thoroughly studied. The test specimens showed good crystalline structure and a smooth, uniform surface. We measured Tc with 4 separate probes. The maximum temperature constant (Tc) was measured to be 143 K at y=0.12.
