In the realm of photoconversion of CO2 into high-value chemicals, the importance of near-infrared (NIR) light is gradually gaining recognition. Relative to ultraviolet (UV) and visible light, NIR light (700-2500 nm), accounting for ca. 50% of solar energy, ...

The heterogeneous speciation of ion-exchanged zeolites hinders a rational understanding of their reactivity. This is particularly the case for Fecontaining zeolites that are widely used in both the activation and decomposition of N 2 O. Herein, we explored ...

Single-walled carbon nanotubes (SWCNTs) are wrapped with single-stranded DNA (ssDNA) to create near-infrared (NIR-II) fluorescent sensors for diverse analytes. However, the interaction between the negatively charged backbone of ssDNA and cations in biologi ...

The electronic structure of metallic Bi2Ir2O7 has been investigated by a combination of soft x-ray absorption spectroscopy, x-ray emission spectroscopy (XES), and resonant inelastic x-ray scattering (RIXS) in the vicinity of the oxygen K edge. The O K-edge ...

Noble metals such as gold and silver have been used extensively for a range of plasmonic applications, including enhancing the fluorescence rate of a dye molecule, as evidenced by numerous experiments over the past two decades. Recently, a variety of doped ...

The orthogonal structure of the widely used hole transporting material (HTM) 2,2 ',7,7 '-tetrakis(N, N-di-p-methoxyphenylamino)-9,9 '-spirobifluorene (Spiro-OMeTAD) imparts isotropic conductivity and excellent film-forming capability. However, inherently w ...

The systematic advances in the power conversion efficiency (PCE) and stability of perovskite solar cells (PSCs) have been driven by the developments of perovskite materials, electron transport layer (ETL) materials, and interfacial passivation between the ...

III-N optoelectronic devices are of great interest for many applications. Visible emitters (based on InGaN) are widely used in the lighting, display and automotive fields. Ultraviolet LEDs (based on AlGaN) are expected to be widely used for disinfection, m ...

We report the resonantly enhanced radiative emission from a single SiGe quantum dot (QD), which is deterministically embedded into a bichromatic photonic crystal resonator (PhCR) at the position of its largest modal electric field by a scalable method. By ...

Thermal stability of perovskite materials is an issue impairing the long-term operation of inverted per-ovskite solar cells (PSCs). Herein, the thermal attenuation mechanism of the MAPbI3 films that deposited on two different hole transport layers (HTL), p ...
