Evaluating the Solvent Stark Effect from Temperature-Dependent Solvatochromic Shifts of Anthracene

Janz, Timais; Güterbock, Manuel; Müller, Fabian; Quick, Martin; Ioffe, Ilya N.; Bischoff, Florian A.; Kovalenko, Sergey A.

The solvent Stark effect on the spectral shifts of anthracene is studied with temperature‐dependent solvatochromic measurements. The Stark contribution ΔvStark to the absorption shift Δvp in polar solvents is measured to ...

Insights into Charge Transfer at an Atomically Precise Nanocluster/Semiconductor Interface

Wang, Yu; Liu, Xiao-He; Wang, Qiankun; Quick, Martin; Kovalenko, Sergey A.; Chen, Qing-Yun; Koch, Norbert; Pinna, Nicola

The deposition of an atomically precise nanocluster, for example, Ag44(SR)30, onto a large‐band‐gap semiconductor such as TiO2 allows a clear interface to be obtained to study charge transfer at the interface. Changing the ...

Type-I Energy Level Alignment at the PTCDA—Monolayer MoS2 Interface Promotes Resonance Energy Transfer and Luminescence Enhancement

Park, Soohyung; Mutz, Niklas; Kovalenko, Sergey A.; Schultz, Thorsten; Shin, Dongguen; Aljarb, Areej; Li, Lain-Jong; Tung, Vincent; Amsalem, Patrick; List-Kratochvil, Emil J.W.; Stähler, Julia; Xu, Xiaomin; Blumstengel, Sylke; Koch, Norbert

Van der Waals heterostructures consisting of 2D semiconductors and conjugated molecules are of increasing interest because of the prospect of a synergistic enhancement of (opto)electronic properties. In particular, ...
