Physical Chemistry Seminar: Towards Molecular photonics

Zoom: 

Abstract:

Photonics – the field of science and technology which manipulates and exploits photons, has been long dominated by solid-state, semiconductor platforms which serve as light sources, modulators and data-storage components. However, recent research suggests that at least some of the functionalities coveted for photonic applications may be found in molecular systems (1).

In this lecture, I will present our investigation of luminescent molecules and stable radical species coupled to plasmonic nano cavities(1, 2). These cavities enhance molecular optical emission by over a thousand-fold, achieving near video rate measurements of luminescence and Raman spectra at the single molecule limit. Our results, based on optical and opto-electrochemical measurements, provide new insights into single molecule light interactions, revealing phenomena linked to optoelectronic properties of molecules, and their interactions with their nano environments, all required for realization of molecular photonic devices.
