“…The wide light absorption around near IR can be associated with the local surface plasmon resonance and light scattering. It is well known that the size, shape, and defect of structures are the dominant parameters regulating the energy band gaps 14 , 16 , 34 , 35 . It is well known that the considerable portion of received sunlight is IR, increasing the earth temperature along a day.…”

In this research, the energy and shielding efficiency of brick, fabricated by clay soil, as a practical building material was reinforced using CuFe2O4 nanoparticles. Initially, the nanoparticles were fabricated using the sol–gel method and then loaded in the brick matrix as a guest. The architected samples were characterized by X-ray powder diffraction (XRD), Fourier transform infrared (FTIR), diffuse reflection spectroscopy (DRS), field emission scanning electron microscopy (FE-SEM), High-resolution transmission electron microscopy (HRTEM), vibrating-sample magnetometer (VSM), differential scanning calorimetry (DSC) thermograms, and vector network analyzer (VNA) analyses. IR absorption of the tailored samples was monitored under an IR source using an IR thermometer. IR absorption and energy band gap attested that inserting the nanoparticles in brick medium led to the acceleration of a warming brick, desirable for energy efficiency in cold climates. It is worth noting that the brick/CuFe2O4 nanocomposite achieved a strong reflection loss (RL) of 58.54 dB and gained an efficient bandwidth as wide as 4.22 GHz (RL > 10 dB) with a thickness of 2.50 mm, meanwhile it shielded more than 58% of the electromagnetic waves at X-band by only a filler loading of 10 wt%. The microwave absorbing and shielding characteristics of the composite are mainly originated from conductive loss, electron hopping, natural and exchange resonance, relaxation loss, secondary fields, as well as eddy current loss. Interestingly, the shielding property of the nanocomposite was significantly generated from its absorbing features, reducing the secondary electromagnetic pollutions produced by the shielding materials applying the impedance mismatching mechanism.

“…Metal or metal oxide NPs can be doped in polymer gel [4] and elaborated on the surface or inside of the optical fibers to develop compact sensing probes [5,6]. A highly sensitive performance has been experimentally demonstrated in many works reported in recent years [7][8][9][10], in which noble metal or metal oxide nano-films or NPs were elaborated on the different fiber structures (microfiber taper, D-shaped, U-shaped interface) to excite long range surface plasmon resonance (LRSPR) or LSPR effect [11]. These fiber sensors have been used for detection of analytes such as hormones, contaminants, etc.…”

Refractive Index and Temperature Sensing Performance of Microfiber Modified by UV Glue Distributed Nanoparticles

Dielectric materials with high refractive index have been widely studied to develop novel photonic devices for modulating optical signals. In this paper, the microfibers were modified by silicon nanoparticles (NPs) and silver NPs mixed in UV glue with ultra-low refractive index, respectively, whose corresponding optical and sensing properties have been studied and compared. The influence from either the morphological parameters of microfiber or the concentration of NPs on the refractive index sensing performance of microfiber has been investigated. The refractive index sensitivities for the microfiber tapers elaborated with silver NPs and silicon NPs were experimentally demonstrated to be 1382.3 nm/RIU and 1769.7 nm/RIU, respectively. Furthermore, the proposed microfiber was encapsulated in one cut of capillary to develop a miniature temperature probe, whose sensitivity was determined as 2.08 nm/°C, ranging from 28 °C to 43 °C.

“…The incorporation of metal nanoparticles into the BHJ solar cell increases the probability of photons being harvested and improved charge carrier mobility, consequently high device performances. ,,−, It is to be recalled that LSPR induces excitation of the surface plasmon waves and increases optical path length within the BHJ TFOSCs by the process of far-field scattering. Lanthanide (Ln 3+ )-containing orthophosphate is known for its application in light-emitting diodes, solar cells, biosensing, and 3D display .…”

Copper-doped lanthanum phosphate (LaPO 4 :Cu) nanocomposites were successfully synthesized using hydrothermal processes for potential application in solar energy harvesting via thin film organic solar cells. LaPO 4 :Cu is attracting interest in application for photovoltaic because of its stability and broad absorption band in the visible spectrum. The structure and morphological properties of the synthesized nanocomposite were studied using high-resolution tunneling and scanning electron microscopy. The solar absorber layer of the solar cells under investigation was composed of a mixture of poly-3hexylthiophene(P3HT) and (6-6) phenyl-C61-butyric acid methyl ester (PC 61 BM) at a 1:1 ratio by weight. The absorber layers are then mixed with LaPO 4 :Cu nanocomposites at different concentrations. The inverted device architecture is employed in this investigation, which is composed of different layers of materials as follows: glass/ITO/ZnO/ P3HT:PC 61 BM: LaPO 4 :Cu/MoO 3 /AL. The results showed that an improved power conversion efficiency (PCE) was observed from all devices containing the nanocomposite. The PCE has increased from 3.58% to a maximum of 6.11% due to the incorporation of the LaPO 4 :Cu nanocomposite. The changes in device performance were attributed to the enhanced optical absorption by virtue of light scattering processes and localized surface plasmon resonance in the photoactive medium. Moreover, the LaPO 4 :Cu nanocomposite-doped inverted solar cells were found to be very stable under an ambient environment.
