MID-INFRARED PHOTODETECTORS

摘要

Nanoparticles, methods of manufacture, devices comprising the nanoparticles, methods of their manufacture, and methods of their use are provided herein. The nanoparticles and devices having photoabsorptions in the range of 1.7 μm to 12 μm and can be used as photoconductors, photodiodes, phototransistors, charge-coupled devices (CCD), luminescent probes, lasers, thermal imagers, night-vision systems, and/or photodetectors.

1. A method comprising:
admixing a mercury(II) salt (Hg2+) and tellurium (Te0) at a temperature below 100° C. thereby forming HgTe nanoparticles; and isolating the HgTe nanoparticles, wherein the nanoparticles exhibit a photoluminescence peak at a wavelength in a range of 1.7 μm to 12 μm.
