Full Color Emission from II-VI Semiconductor Quantum Dot-Polymer Composites

Abstract

Nearly full color emission has been achieved using quantum dot (QD)–polymer composites. The fluorescence of the resulting composites spans the entire visible range with narrow emission profiles and high photoluminescence (PL) quantum yields. Moreover, mixed colors are easily produced by controlling the mixing ratio of different sized QDs. The Figure shows end-on rods of QD–polymer composites excited from underneath by a UV lamp.
