A direct oriented-attachment growth of lead-chalcogenide mid-infrared nanocrystals film on amorphous substrates

A direct oriented-attachment (OA) growth of lead-chalcogenide nanocrystals (NCs) on amorphous substrates leads to the synthesis of (111) dominated PbSe NCs for the first time. These NCs uniformly assembled on glass slides forming mirror-like thin films of tunable quantum confining effect in the mid-infrared spectrum.
