Due to their unique optical property, low toxicity, high hydrophilicity, and low cost, sulfur
quantum dots (SQDs), an emerging luminescent nanomaterial, have shown great potential …

Infrared photodetectors (PDs) based on epitaxial semiconductors occupy the majority of the
market, but their high cost from material growth and device integration limits their application …

Various potential applications of quantum dots (QDs) require knowledge of their optical
nonlinearities. In this review, the third-order nonlinearities responsible for the saturable …

Recently, lanthanide‐based 0D metal halides have attracted considerable attention for their
applications in X‐ray imaging, light‐emitting diodes (LEDs), sensors, and photodetectors …

Colloidal quantum dots (CQDs) are of interest for optoelectronic devices because of the
possibility of high-throughput solution processing and the wide energy gap tunability from …

Discovery of infrared radiation (IR) was an important step in understanding the hidden
secrets of nature, which could be unraveled only after “seeing” this invisible spectrum. This …

A simple photoconductor structure based on a HgTe colloidal quantum dot (CQD) film on a
field-effect transistor substrate is analyzed to provide quantitative information on the mobility …

Colloidal quantum dots are of increasing interest for mid-infrared detection and emission,
but device performances will vastly benefit from reducing the non-radiative recombination …

There is an emergent need for low-cost, uncooled detectors operating in the mid-wavelength
infrared. Here, we report the first Schottky junction diode that utilizes intraband Ag2Se …

We synthesized the colloidal mercury telluride quantum dots (QDs) and analyzed their low-
order nonlinear optical properties using 1064 nm and 532 nm, 10 ns pulses. HgTe QDs …
