Nonlinear absorption in Au films: Role of thermal effects

N Rotenberg, AD Bristow, M Pfeiffer, M Betz… - Physical Review B, 2007 - APS
The effective nonlinear optical absorption coefficient β eff is measured for 20− nm-thick Au
films at 630 nm as a function of pulse width. The z-scan measurements show that β eff …

A tyrosine aminotransferase involved in tocopherol synthesis in Arabidopsis

D Riewe, M Koohi, J Lisec, M Pfeiffer… - The Plant …, 2012 - Wiley Online Library
The metabolic function of the predicted Arabidopsis tyrosine aminotransferase (TAT)

Enhancing the optical excitation efficiency of a single self-assembled quantum dot with a plasmonic nanoantenna

M Pfeiffer, K Lindfors, C Wolpert, P Atkinson… - Nano …, 2010 - ACS Publications
We demonstrate how the controlled positioning of a plasmonic nanoparticle modifies the
photoluminescence of a single epitaxial GaAs quantum dot. The antenna particle leads to an …

Watching a single fluorophore molecule walk into a plasmonic hotspot

L Xin, M Lu, S Both, M Pfeiffer, MJ Urban, C Zhou… - Acs …, 2019 - ACS Publications
Plasmonic nanoantennas allow for enhancing the spontaneous emission, altering the emission
polarization, and shaping the radiation pattern of quantum emitters. A critical challenge …

Eleven nanometer alignment precision of a plasmonic nanoantenna with a self-assembled GaAs quantum dot

M Pfeiffer, K Lindfors, H Zhang, B Fenk, F Phillipp… - Nano …, 2014 - ACS Publications
Plasmonics offers the opportunity of tailoring the interaction of light with single quantum
emitters. However, the strong field localization of plasmons requires spatial fabrication accuracy …
