摘要
Paint by number: High-quality InAs quantum dots (QDs) for near-IR fluorescence (see picture) were synthesized by exploiting interparticle diffusion and self-focusing instead of using the traditional focusing of size distribution. InAs/CdSe core-shell QDs were grown and analyzed by a technique combining TEM and elemental analysis to determine the sizes and molar extinction coefficients of the extremely small InAs particles. © 2008 Wiley-VCH Verlag GmbH & Co.
