The electronic properties of co-evaporated mixtures (blends) of manganese phthalocyanine and the fullerene C60 (MnPc:C60) have been studied as a function of the concentration of the two constituents using two supplementary electron spectroscopic methods, photoemission spectroscopy (PES) and electron energy-loss spectroscopy (EELS) in transmission. Our PES measurements provide a detailed picture of the electronic structure measured with different excitation energies as well as different mixing… 
Energy-level alignment at interfaces between manganese phthalocyanine and C60
The results demonstrate that MnPc/C60 interfaces are hardly suited for application in organic photovoltaic devices, since the energy difference of the two lowest unoccupied molecular orbitals (LUMOs) is rather small.
Synthesis and Characterization of Molybdenum Phthalocyanine as Target Material for High Specific Activity Molybdenum-99 Production
High specific activity is a necessity in the fabrication of 99Mo/99mTc radioisotope generators. Recoil reaction, or the Szilard-Chalmers effect, is a method that could be used as an alternative
Transverse resonance island buckets for synchrotron-radiation based electron time-of-flight spectroscopy.
The scheme applied here for selecting the photons originating from a particular orbit by optical imaging has been used before in fs slicing applications and may be relevant for the BESSY VSR project of the Helmholtz-Zentrum Berlin.
The U125 insertion device beamline at the Metrology Light Source.
With the results from the beamline commissioning, an uncertainty budget for all relevant radiometric quantities was established and attention is paid to the suppression of unwanted spectral contributions from higher diffraction orders, and to the monitoring of the radiation intensity during the measurements.
Specific Operation Modes at the Metrology Light Source
The high flexibility of the Metrology Light Source (MLS) allows application of various nonstandard user modes adapted to the specific needs of their users. We report on some of them including a mode


Electronic states and the influence of oxygen addition on the optical absorption behaviour of manganese phthalocyanine.
The reaction of MnPc with atmospheric molecular oxygen leads to deviations in peak intensities but does not change the fundamental characteristics of the spectra, while the reaction with oxygen changes the spin state from S = 3/2 to S = 1/2.
Electronic properties and morphology of Cu-phthalocyanine—C60 composite mixtures
Phthalocyanines in combination with C60 are benchmark materials for organic solar cells. Here, we have studied the morphology and electronic properties of co-deposited mixtures (blends) of these
Phthalocyanine/C60 composites as improved photosensitive materials
We have investigated the influence of C60-fullerenes as a dopant in thin layers of phthalocyanines (Pc). We expect that C60 acts as an electron acceptor. Charge transfer of an electron from the first
