From: Mass spectrometric monitoring of interfacial photoelectron transfer and imaging of active crystalline facets of semiconductors

Figure 1

(a) Principle of fluorescence spectroscopy-based approach. (b) Principle of mass spectrometry-based approach. (c) Charge distribution of neutral juglone and the radical anion of juglone. (d) Energy profile of photoelectron capture by neutral juglone. (e) Formation of anionic ground states through ultrafast internal conversion. Purple ovals: fluorogenic chromophores. Black balls: molecules adsorbed on different sites of semiconductor facets. Coloured balls (red, green, orange and blue balls): resultant intermediates and products of potocatalytic reactions. V1, V2 and V3: the voltages applied to the extraction plate, hexapole and aperture, respectively.
