Based on the principle of super-symmetric lens with quadratic phase gradient transformation, combined digital coding metasurface, we propose a wide-angle coded metalens for focusing control in two-dimensional space. This achieves focus shift x-direction by changing oblique incidence angle incident wave, and y-direction combining convolution digitally metasurface to achieve flexible light plane. The unit is mainly composed three-layer metal structure two layers medium, transmission obtained...
A red-emitting phosphor, Eu2+-activated Ca4(PO4)2O phosphor was synthesized by conventional solid-state reaction. X-ray powder diffraction confirmed the phase formation. The band gap of estimated to be about 4.75 eV from diffuse reflection spectrum. excitation and emission spectra, concentration dependence intensity were investigated. results showed that under at 460 nm, Ca4(PO4)2O:Eu2+ phosphors exhibit strong red centered 665 optimum Eu2+ in is 0.07 mol per Ca2+ ions. nature ion...
Abstract All dielectric nanospheres with low loss and ultra‐compact characteristics can be effectively applied in nanophotonics the visible infrared ranges. The unidirectional forward scattering azimuthally symmetry achieved by simple nanosphere. physical origin of this directionality attributed to interference effect electric magnetic resonances induced nanoshperes. For a single nanosphere spectrally overlapping resonance quadrupoles further enhance magnitude scattering. homodimers, pattern...
Abstract We propose a multiband metamaterial absorber consisting of silicon brick array on metal substrate in infrared range. Using the regular hexagon bricks, absorption rate can reach to 90% over bandwidth 100 nm, and four peaks with more than 98% be obtained. The is independent polarization angle. performance attributed primary cavity mode Mie resonance bricks. Importantly, when all‐dielectric bricks are replaced by metal‐dielectric‐metal sandwich structure, above 75% 200 nm realized, it...
We report a polarization-independent unnaturally high refractive index metamaterial. It is found that the effective permittivity of designed metamaterial can be drastically increased by capacitive coupling effect. Also, permeability reducing diamagnetic effect designing thin structure. In our work, single-layer multi-band metamaterials with peak achieving to 26.8 at 0.9 THz demonstrated. Furthermore, three-dimensional possessing more than 85 around 0.91 constructed double-layer tricyclic...
Abstract As a popular artificial composite material emerging in recent years, metasurfaces are one of the most likely devices to break through volume limitation conventional optical components due their compact structure, flexible materials, and high modulation resolution beam. With unique arrangement units or made special metasurface can effectively modulate incident light's amplitude, phase, polarization, frequency, thus realizing applications such as communication, imaging, sensing, beam...
Osteoporosis (OP) is one of the most common bone diseases, especially in women after menopause. Increasing evidence shows that non-coding RNAs are implicated pathogenesis OP. In this study, based on published circular RNA profiling data between OP patients and healthy controls, we found circRNA_0001795 (circ_0001795) downregulated samples, which was further validated samples collected study. We therefore investigated functional role molecular mechanism circ_0001795 osteogenic differentiation...
Green- and yellow-emitting α- β-Zn2SiO4:Mn2+ nanocrystals incorporated into glass ceramics have been selectively synthesized successfully by a conventional melt-quenching method. XRD, EPR, TEM, EDS, electronic optical spectroscopy were employed to discriminate the formation of further elucidate coordination environment Mn2+ in Zn2SiO4:Mn2+ practical material. The combination crystal field calculation with experimental absorption excitation spectra enables us interpret spectroscopic features...
