“…Each specific peak is prepared according to the JCPDF card number: 361451. The diffraction peaks of the integrated ZnO nanoparticles are elongated after calcination as they preserve the nanostructure [5,6 The apex development is also caused because of high strain, instrumental screws up, and so forth [7]. We use the Scherrer relationship to find the bulk culture of ZnO nanoparticles [8];…”

XRD and SEM images of ZnO nanoparticles prepared by the precipitation method allow investigation of their morphology and morphological refinement. No contamination was observed in the XRD spectrum and SEM confirmed that the nanoparticles were wellcoordinated ZnO at 30 nm size. UV-Vis spectroscopy was used to tune the optical properties and they appeared not to be fixed at 3.34 eV. The band gap of semiconductor materials makes them competitive for solar cell applications. The O-rich stoichiometry measured by XPS may be a direct result of zinc deficiency. Therefore, ZnO nanoparticles were prepared to fabricate secretory solar cells (DSSCs). From the perspective of J-V, open circuit voltage (Voc), barrier thickness (Jsc), fill factor (FF) and efficiency (η) were not chosen as much as possible and the quality was calculated as 0.65V, 6.26mA. , 62.2% and 1.96% respectively at 100mW/cm2 .

The advancement in nanotechnology has completely revolutionized various fields, including pharmaceutical sciences, and streamlined the potential therapeutic of many diseases that endanger human life. The synthesis of green nanoparticles by biological processes is an aspect of the newly emerging scientific field known as "green nanotechnology". Due to their safe, eco-friendly, nontoxic nature, green synthesis tools are better suited to produce nanoparticles between 1 and 100 nm. Nanoformulation of different types of nanoparticles has been made possible by using green production techniques and commercially feasible novel precursors, such as seed extracts, algae, and fungi, that act as potent reducing, capping, and stabilizing agents. In addition to this, the biofunctionalization of nanoparticles has also broadened its horizon in the field of environmental remediation and various novel therapeutic innovations including wound healing, antimicrobial, anticancer, and nano biosensing. However, the major challenge pertaining to green nanotechnology is the agglomeration of nanoparticles that may alter the surface topology, which can affect biological physiology, thereby contributing to system toxicity. Therefore, a thorough grasp of nanoparticle toxicity and biocompatibility is required to harness the applications of nanotechnology in therapeutics.

Using a soft chemical process that involves nitrates and heat annealing, nanoparticles of undoped ZnO and praseodymium, aluminum-codoped ZnO may be produced. XRD, SEM with EDS, and FTIR analysis determine nanocatalyst structures, morphologies, and chemical bonding. PL and UV spectroscopy examines optical characteristics. The peak in the FTIR spectral line at 714 cm-1 in the study indicates M-O stretching in the samples and ZnO's interaction with the Pr and Al matrix. XRD patterns indicated prepared nanoparticles with nanosizes ranging from 40.07 to 38.65 to 36.84 to 38.87 to 39.91 nm. SEM analyzed nanoparticle size, shape, and interaction with the Pr and Al matrix. EDS determined NPs purity. UV-vis spectra of ZnO-Pr/Al nanocomposites showed UV absorption similar to ZnO nanoparticles. Doping ZnO with Pr and Al shrinks the bandgap and slows photogenerated electron-hole pair recombination without changing its crystalline structure.
