From Molecular Design to Optical Anisotropy: Orientation Control in BODIPY Langmuir-Blodgett Films
Lilia Huynh, Jason Bessonnet, Lucas Fr{é}d{é}ric +7
Molecular orientation within ultrathin films is a critical factor in controlling their optical and electronic properties for surface-based photonics and optoelectronics. In this st…
Impacts of annealing on structural and photophysical properties of zinc phthalocyanine adsorbed on graphene
Gautier Creutzer, Quentin Fernez, Nataliya Kalashnyk +5
We report the demonstration and analysis by combined scanning-tunneling-microscopy and optical microspectroscopy of a 2D phase change experienced by a self-assembled zinc phthalocy…
Determinant role of size-dependent electron relaxation processes in the nonlinear luminescence emission of resonantly excited gold nanorods
Céline Molinaro, Sylvie Marguet, Ludovic Douillard +2
The two-photon luminescence (TPL) of gold nanoparticles (NP) was shown to result from the excitation of hot carriers, the plasmonic NP resonances playing an important role both for…
Two-photon luminescence of single colloidal gold nanorods: revealing the origin of plasmon relaxation in small nanocrystals
Celine Molinaro, Yara El Harfouch, Etienne Palleau +5
The two-photon luminescence (TPL) of small 10 nm x 40 nm colloidal gold nanorods (GNR) is investigated at the single object level, combining polarization resolved TPL and simultane…
