The short-wavelength infrared light (SWIR) sensor currently used requires a Peltier cooler and a diffraction grating spectroscope owing to its detection principle. Thus, realizing a low-cost and miniaturized SWIR imaging device remains challenging and has limitations for practical applications. In this ...

In continuing research, the core/shell structures have been introduced to NIR dye-sensitized nanocrystals, aiming to solve the issues of surface-related luminescence quenching. In these dye-sensitized core/shell nanocrystals, the organic fluorophore molecules could absorb infrared light radiation and trans...

different evolution in photocurrent, and the corresponding relationship between the photocurrent ratio and wavelength can be easily expressed as a monotonic function, via which the wavelength in a broad range from deep ultraviolet (265 nm) to near infrared light (1550 nm) can be easily calculated....
However, the excitation wavelength of conPET systems mainly focused on short wavelength visible light, leading to photodamage and incompatibility with large-scale reactions. Herein, we report on conPET systems triggered by near-infrared (NIR) and red light. Specifically, a blue-absorbing conPET ...
Most single-layer transition metal dichalcogenides (TMDs) are direct-gap semiconductors, which can exert desirable optical properties in the near-infrared wavelength range [14,15]. MoS2 is a typical transition metal chalcogenide material, of which the single-layer sheets formed by covalent bonds ...
as verified by in situ grazing incidence wide-angle X-ray spectroscopy. We tailor the distribution of the perovskites to drive balanced ultrafast excitonic energy transfer to the QDs. The resulting LEDs operate in the short-wavelength infrared region, an important regime for imaging and sensing appl...
