Abstract
An infrared up-conversion device for converting LWIR radiation to NIR radiation includes a distribution of core-shell nano-sized particles within a transparent binder material. The core-shell particles can be composed of a HgTe core and a CdTe shell. The up-conversion device can be used with a NIR imager to function as an LWIR imager without the need for cryogenic cooling.
