“…Furthermore, the growing literature has provided a study on the optical properties of PVA containing several rare-earth sources. For example, Keikhaei et al investigated the optical properties of PVA with Nd 2 O 3 using UV-Vis absorption spectroscopy [ 11 ]. Meanwhile, polyvinyl pyrrolidone (PVP) is an excellent polymer which was designed to be a coating and additive to several materials [ 12 , 13 , 14 ].…”

In this present work, a PVA/PVP-blend polymer was doped with various concentrations of neodymium oxide (PB-Nd+3) composite films using the solution casting technique. X-ray diffraction (XRD) analysis was used to investigate the composite structure and proved the semi-crystallinity of the pure PVA/PVP polymeric sample. Furthermore, Fourier transform infrared (FT-IR) analysis, a chemical-structure tool, illustrated a significant interaction of PB-Nd+3 elements in the polymeric blends. The transmittance data reached 88% for the host PVA/PVP blend matrix, while the absorption increased with the high dopant quantities of PB-Nd+3. The absorption spectrum fitting (ASF) and Tauc’s models optically estimated the direct and indirect energy bandgaps, where the addition of PB-Nd+3 concentrations resulted in a drop in the energy bandgap values. A remarkably higher quantity of Urbach energy for the investigated composite films was observed with the increase in the PB-Nd+3 contents. Moreover, seven theoretical equations were utilized, in this current research, to indicate the correlation between the refractive index and the energy bandgap. The indirect bandgaps for the proposed composites were evaluated to be in the range of 5.6 eV to 4.82 eV; in addition, the direct energy gaps decreased from 6.09 eV to 5.83 eV as the dopant ratios increased. The nonlinear optical parameters were influenced by adding PB-Nd+3, which tended to increase the values. The PB-Nd+3 composite films enhanced the optical limiting effects and offered a cut-off laser in the visible region. The real and imaginary parts of the dielectric permittivity of the blend polymer embedded in PB-Nd+3 increased in the low-frequency region. The AC conductivity and nonlinear I-V characteristics were augmented with the doping level of PB-Nd+3 contents in the blended PVA/PVP polymer. The outstanding findings regarding the structural, electrical, optical, and dielectric performance of the proposed materials show that the new PB-Nd+3-doped PVA/PVP composite polymeric films are applicable in optoelectronics, cut-off lasers, and electrical devices.

“…2. It can be observed that the broadband at 3455 cm − 1 for pure oxide while adding silver NPs does not cause a noticeable shift that O-H stretching vibration of the -OH group appears at 3448 cm − 1 [14]. The revealing absorption peak at 3554 cm − 1 is attributed to thio-urea residual N-H stretching [15].…”

“…The revealing absorption peak at 3554 cm − 1 is attributed to thio-urea residual N-H stretching [15]. The Neodymium oxide (Nd 2 O 3 ) NPs strong band centered at 669 cm − 1 is attributed to Nd-OH which shows signi cant diminishing with adding Silver nano-particles [14]. The centered bands at 588 cm − 1 was because of -O stretching of Nd [13].…”

Our study focuses on optical behavior, methylene blue (MB) dye degradation potential of pure Neodymium oxide (Nd2O3 NPs), and Silver (Ag)/Neodymium oxide (Nd2O3) nano-composite, besides demonstrating their antibacterial performance in the resolve of silver and trioxide mineral interaction with different types of bacterial species. For illustration, S.aureus, and E.Coli give a significant response with clear enlargement of inhibition zone under Ag NPs adding. S.aureus inhibition area widened from 9.3 ± 0.5 mm for pure Neodymium oxide (Nd2O3) to 16.7 ± 0.4 mm for Ag/Nd2O3 nano-composite, while Escherichia coli inhibition zones jumped from 8.8 ± 0.4 mm for Neodymium oxide to15.9 ± 0.3 mm for Ag/ Nd2O3. Additionally, generally optical behavior shows clear band-gap narrowing with merging Ag NPs, which enhances boosting electronic localization. That direct and direct transitions dropped from (6.7 to 6.1) and (5.2 to 2.9 e.V), respectively. Regarding the MB degradation, Mixed System Ag/ Nd2O3 shows more efficient Methylene blue degradation than pure Nd2O3 in that the MB concentration fell to almost half of its starting point at 150 minutes, while pure Nd2O3 reached 33% after 150 minutes. Moreover, TEM displays the studied compositions microstructures confirming the good distribution of Ag NPs (average size 9.2 nm) upon Nd2O3. The results interpretations boost usage of such composites in sensors industries, and water treatment.

“…Thus in principle, it is recommended to use materials with low absorption at the emission and pump wavelength. As a result, polymeric materials have been newly considered as an attractive host matrix for rare earth ions due to their unique properties, including reasonable cost, straightforward fabrication procedure, excellent precise refraction coefficients, well thermal stabilities, as well as great transparency in wide-ranged spectral regions (visible and near-infrared) [4,5].…”

This research presents a novel optical polymer of polyvinyl alcohol (PVA), as a host matrix, doped with various weight concentrations of Neodymium oxides (Nd2O3) metals, as a filler, where Nd2O3/PVA polymeric thin films were synthesized to be successfully utilized as a dynamic media for polymeric lasers. The solution casting method, simple and low-cost, was applied to homogeneously prepared composite films of Nd2O3-doped PVA. The crystallinity of the structures, the uniformity of the films, and the interactions among the Nd2O3 doping metals and the PVA matrix were approved via x-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis. The remarkable effects of various weight concentrations of Nd2O3 doping on the optical parameters for Nd2O3/PVA composite polymeric thin films were determined using a UV–vis spectrophotometer. Kramers-Kroning’s approach was exploited to evaluate the linear refractive index (n), energy bandgap (E g ), and nonlinear optical effects for the proposed polymers.Moreover, a manual Z-scan method was applied to study the optical limiting effects using red He-Ne laser and green diode laser. This study illustrated some advantages of the outcome of the semi-crystalline structure, amazing linear optical parameters, including low optical energy bandgaps, brilliant dielectric constant, substantial optical limiting, as well as excellent nonlinear optical parameters of the proposed Nd2O3/PVA nanocomposite films. Thus, it is possible to conclude that the synthesized Nd2O3/PVA polymeric films play central roles in different promising, practical optoelectronic applications, such as lasers, optical filters, optical communication, light-emitting diodes, and optical switching.
