Silicon/2D-material photodetectors: from near-infrared to mid-infrared

Light: Science & Applications, 2021
Two-dimensional materials (2DMs) have been used widely in constructing photodetectors (PDs) because of their advantages in flexible integration and ultrabroad operation wavelength range.

The Resolved Near-Infrared Extragalactic Background

, 2010
We present a current best estimate of the integrated near-infrared (NIR) extragalactic background light (EBL) attributable to resolved galaxies in J, H, and Ks.

Sub-Pixel Response Measurement of Near-Infrared Sensors [PDF]

, 2006
Wide-field survey instruments are used to efficiently observe large regions of the sky. To achieve the necessary field of view, and to provide a higher signal-to-noise ratio for faint sources, many modern instruments are undersampled.

Near-infrared spectroscopy of autunites

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2005
NIR spectroscopy has been applied to the study water in the interlayer of the autunite minerals. The spectra of autunites and metaautunites in the first HOH fundamental overtone are different and the spectra of autunites of different origins in the 6000-7500 cm(-1) region are considerably different.

Near-infrared photoluminescence of Portland cement

Scientific Reports, 2022
Portland cement emits bright near-infrared photoluminescence that can be excited by light wavelengths ranging from at least 500–1000 nm. The emission has a peak wavelength near 1140 nm and a width of approximately 30 nm.

Chemistry with Red and Near Infrared Light

CHIMIA, 1991
Opportunities are explored to initiate controlled chemistry by photolysis with long-wavelength visible and near infrared light. In one direction, bimolecular reactions are induced by exciting collisional pairs in a solid matrix to energy ...

All-Sky Near Infrared Space Astrometry [PDF]

, 2019
Gaia is currently revolutionizing modern astronomy. However, much of the Galactic plane, center and the spiral arm regions are obscured by interstellar extinction, rendering them inaccessible because Gaia is an optical instrument.
