Prospective work shall continue the theoretical analysis of ultrafast excited state dynamics in hybrid systems which are formed by molecular complexes, semiconductor nanocrystals, and metal nanoparticles. This also covers the computation of transient optical spectra. Therefore, we further apply the semi-empirical type of description which has been developed in the first founding period. Photoinduced charge separation at the molecule/ZnO interface will be studied in a first sub-project. A second sub-project focusses on electronic excitation energy transfer in a tubular dye aggregate and between this aggregate and CdTe nanocrystals.

未来的工作将继续在混合系统，这是由分子复合物，半导体纳米晶体，和金属纳米粒子形成的超快激发态动力学的理论分析。这也包括瞬态光谱的计算。因此，我们进一步应用在第一个创始时期发展起来的半经验型描述。第一个子项目将研究分子/ZnO界面的光致电荷分离。第二个子项目的重点是电子激发能量转移在管状染料聚集体和这种聚集体和碲化镉纳米晶体。
