Hybrid polymer/nanocrystals structures: fabrication and studies of energy transfer, charge generation and transport

由半导体聚合物和强发光半导体纳米晶体组成的杂化结构通过低成本的湿化学可加工性和高度饱和的发射颜色的结合，为显示技术提供了良好的前景，这对全彩大面积平板显示器的发展具有重要意义。其他可能的应用领域是有机-无机混合发光二极管和太阳能电池。该项目致力于通过适当选择聚合物的官能团，开发直接附着在半导体纳米晶体上的半导体聚合物的智能组合，为新型复合功能材料铺平道路。研究和优化这些材料中的能量转移、电荷产生和输运，对提高聚合物/纳米晶体杂化器件的效率有有益的影响。

Hybrid structures consisting of semiconducting polymers and strongly luminescent semiconductor nanocrystals offer favourable perspectives in display technology through a combination of low cost wet-chemical processability with a highly saturated emission colour, which is of importance to the development of full colour large area flat panel displays. Further fields of possible applications are hybrid organic-inorganic light-emitting diodes and solar cells. This project addresses the development of smart combinations of semiconducting polymers that are directly attached to semiconductor nanocrystals through a proper choice of functional groups of the polymers, paving the way to novel composite functional materials. Investigation and optimisation of energy transfer, charge generation and transport in these materials will be carried out, being of beneficial impact towards improved efficiency of hybrid polymer/nanocrystal devices.
