Cd3P2 QDs emitting in the SWIR through overgrowth of cadmium phosphide clusters

Abstract

Cd₃P₂ quantum dots (QDs) are promising candidates for short-wave infrared (SWIR) applications. Producing QDs with SWIR emission and sharp spectral features is challenging. In this study, we show that overgrowth of Cd₃P₂ clusters extends the emission of Cd₃P₂ QDs into the SWIR. The resulting QDs are promising for imaging and telecom applications.
