Engineering optical properties of doped quantum dots by chemical reactions

Abstract

Understanding the origin of emitting species and the contribution of the surface ions in quantum dots Qdots towards the overall photoluminescence are important and much remains to be explored The current thesis primarily deals with the decisive role of the surface ions in doped Qdots and their potential to react with external chemical species thereby tuning their optical properties This was approached with three different binary quantum dots Qdots having the same host but different dopan
