Abstract

We present the theory of the thermally activated photoluminescence upconversion, also known as anti-Stokes photoluminescence (ASPL), based on the quantum dot (QD) polaron effect and explaining all the principal features of the ASPL in colloidal solutions of chemically grown nanocrystals (NCs). The results obtained by Monte-Carlo simulations reproduce all the experimentally observed ASPL trends in colloidal NC solutions and are being extended to dense QD systems, such as films composed by layers of closely packed NCs. © 2010 Wiley-VCH Verlag GmbH & Co.
