Offer Description

Optical detection is a key tool in microscopy and for the design of sensors, because it allows for the real time quantitative monitoring of several environmental or biological parameters simultaneously. Multiplexing is generally based on fluorophores with different emission wavelengths. However, it is also possible to use the emission lifetime to create a contrast. For example, FLIM (Fluorescence-lifetime imaging microscopy) technique is able to map dyes in fonction of their fluorescence lifetime. Moreover, « time gated » method, discard the majority of off target signals by introducing a delay between the excitation and the measurement.
The postdoctoral researcher will be in charge of synthesizing (5-6 steps) new dyes with long emission lifetimes. Then He/She will study their optical properties in solution and solid state. This study will include the measurement of fluorescence quantum yields, phosphorescence, and emission lifetime.
