Gallium lanthanum sulphide glasses for near-infrared photonic applications
… loss of GLS glasses. <br/><br/>The optical absorption at 1.55 and 1.7 µm was measured for the first time by laser absorption calorimetry using a tunable free electron laser source. To this end, a calorimeter was designed and commissioned and an improved model for the heat flow analysis of …

Development and testing of thin photocatalyst films
… of photoactivity.<br/><br/>The development of a photoinduced absorption spectroscopy (PIAS) setup is described, as well as its use to investigate the photoreduction of oxygen by monitoring the formation and decay of transients associated with photogeneration of electrons in CdS paste films, …

Electronic and optical properties of InAs nanocrystals
… calculated interband (valence-to- conduction) absorption spectra reproduce the features observed experimentally both qualitatively and quantitatively. The results relative to intraband (valence-to-valence and conduction-to-conduction) absorption successfully reproduce the recently measured …

Photoinduzierte Absorptionsspektroskopie an organischen, photovoltaisch aktiven Donor-Akzeptor-Heteroübergängen
… nahezu unabhängig ist. Mittels photoinduzierter Absorptionsspektroskopie und zeitaufgelöster Fluoreszenzmessung wurde der Energie- und Elektronentransfer zwischen DCVnT und C60 entlang der homologen Reihe der DCVnT untersucht. Eine wesentliche Feststellung ist die Korrelation zwischen …
