Abstract

The effect of the outer surface of core/shell nanocrystals on the fluorescence quantum yield was observed for In As/InP and InAs/CdSe core/shells (see picture). For InAs/CdSe we observed substantial enhancement of the fluorescence quantum yield compared to the InAs core, and up to two times larger than the laser dye IR-140. Such core/shell nanocrystals have potential use as biological fluorescent markers in the near IR spectral range.
