Abstract

In this effort, we present the most recent progress towards fabrication and testing of quantum dot composite materials. These materials are important steps towards easy integration of a light source on silicon. Quantum dot composites are formed by incorporating quantum dots in a host material that acts to protect and maintain the characteristics of the quantum dots, as well as to act as a patternable matrix for lithography and etching. In this effort, commercially available IR emitting PbS quantum dots (Evident Technologies) were incorporated with PMMA and poly (hexyl methacrylate) and their photoluminescence spectra was examined over time. A large shift in the photoluminescence emission peak over the course of several days was observed in all composites. This could be due to oxidation despite being in a host.
