Multicolor Emission of Small Molecule-Based Amorphous Thin Films and Nanoparticles with a Single Excitation Wavelength

Fluorescent organic nanoparticles (FON) made of small molecules recently arouse considerable interest in biomedical imaging and opto-electronics as potential microlasers or emitting displays.2 Their collective emission largely enhanced with respect…

Ruthenium(II) Complexes for Two-Photon Absorption-Based Optical Power Limiting

Long-lived excitation: Novel bifluorene-substituted 1,10-phenanthroline-based RuII coordination complexes are presented (see picture). They fulfil several requirements for optimized optical power limiting in the visible-NIR, as they are stable,…

Scanning-less wide-field single-photon counting device for fluorescence intensity, lifetime and time-resolved anisotropy imaging microscopy

A scanning-less single-photon counting system for FLIM and fluorescence anisotropy wide-field imaging is described and characterized in this paper. The two polarizations of the fluorescence are divided by a Glan prism and acquired at the same time…

Organic crystals for second harmonic generation switching based on anil photochromes

In photochromic materials, we demonstrated that non-linear optical (NLO) properties such as second harmonic generation (SHG) can be switched reversibly by alternate UV and visible irradiations. We report here on the design of materials fulfilling…
