Resonance Raman Spectral Imaging of Intracellular Uptake of β-Carotene Loaded Poly(D,L-lactide-co-glycolide) Nanoparticles
The use of nanoparticles for drug delivery has been drawing considerable attention in pharmaceutical research. With increasing diversity and potential of various carrier systems, it is important to study...
PublicationsA Novel Ru(II) Polypyridine Black Dye Investigated by Resonance Raman Spectroscopy and TDDFT Calculations
The optical properties of a new (bipyridine)2Ru(4H-imidazole) complex presenting a remarkable broad absorption in the visible range are investigated. The strong overlap of the absorption with the solar...
PublicationsStructural control of photoinduced dynamics in 4H-imidazole-Ruthenium dyes
The photoinduced dynamics of a series of terpyridine 4H-imidazole-Ruthenium complexes, which constitute a new family of panchromatic sensitizers, is investigated. The dynamics involves two excited states...
PublicationsFigures of merit of thermal radiation sensors
Figures of merit condensing the performance parameters of radiation sensors such as responsivity, noise equivalent power and time constant in a single number can be useful for rating the performance of...
PublicationsSolid Phase Epitaxy of Silicon Thin Films by Diode Laser Irradiation for Photovoltaic Applications
High temperature solid phase epitaxial crystallization of amorphous silicon layers prepared by electron beam evaporation (EBE) is investigated. By using a cw diode laser for heating the films rapidly (in...
PublicationsField-Effect Transistors based on Silicon Nanowire Arrays: Effect of the Good and the Bad Silicon Nanowires
Aligned arrays of silicon nanowires (aa-Si NWs) allow to exploit their nanoscale properties in a scalable way. Previous studies explored the influence of the number, doping density, and diameter of the...
PublicationsWet chemically prepared silicon nanowire arrays on low-cost substrates for photovoltaic applications
Silicon nanowire (SiNW) based solar cells are a promising candidate for third generation solar cells with high effi¬ciency, which will further reduce the cost of the PV modules, making it competitive...
PublicationsTemperature dependent optical properties of amorphous silicon for diode laser crystallization
The temperature dependent optical parameters n and k of amorphous silicon deposited by electron beam evaporation were determined at the wavelength of 808 nm. This was achieved by fitting an optical model...
