PACS numbers: 61.05.cp, 68.37.Hk, 68.37.Og, 78.40.-q, 78.67.Hc, 81.07.Ta, 81.16.Be

Polymer capping matrix plays an important role in the synthesis of quantum dots via chemical methods. In this article, polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) polymers are used as capping matrix for the synthesis of quantum dots. Quantum dots of zinc oxide are directly synthesized from ZnO powder by thermal quenching methods on PVA and PVP capping matrix, and standard characterization techniques are utilized to characterize the samples. Thereafter, comparative analysis for the properties of ZnO quantum dots for PVA and PVP is presented.

Keywords: quantum dots, quenching, polyvinyl alcohol, polyvinyl pyrrolidone, nanotechnology
