Colloidal semiconductor nanocrystals have been widely studied due to their size-dependent optical properties as well as the potential applications in the field of optic s and optoelectronics.To develop these applications,there is an increased need to embed them into transparent matrix.The as-prepared nanocomposite materials show great promise as they can provide the necessary stability and processability for these im portant applications.However,preparation of lar ge size,high transparent and highly lum inescent QDs based nanocom posites is still a great challenge due to well-known ligand exchange induced PL quenching effects and aggregation induced scattering.We recently developed high quality nanocyrstals(CuInS 2 QDs and Cd x Zn 1-x Te QDs),and worked on the surface and interface engineering to incorporate these luminescen t nanocrystals into transp arent matrices and studied the applications in light-emitting diodes and 3D display applications.

棉花是我国种植最为广泛的经济作物，是纺织工业最重要的原料，在我国国民经济中占有重要的地位。近年来随着纺织工业技术的不断发展，人们对棉纤维品质提出了更高的要求。要想通过传统的育种方法同时改良纤维品质和产量性状存在较大的困难。分子标记技术辅助育种可显著提高育种效率，其目的是构建饱和的连锁遗传图谱，并定位数量性状基因座（quantitative trait locus，QTL）。目前从已构建的遗传图谱（
