Optical imaging through scattering media via magnetically modulated fluorescence [PDF]
, 2014 A weak (< 1000 G) magnetic field can influence photochemical processes through its effect on electron spin dynamics in a photogenerated radical pair. In a solution of pyrene and dimethylaniline this effect manifests as magnetic field-dependent exciplex ...

Origin of spectral broadening in pi-conjugated amorphous semiconductors [PDF]
, 2002 We present a study of the picosecond fluorescence dynamics of pi-conjugated semiconducting organic dendrimers in the solid state. By varying the degree of branching within the dendrons, referred to as the dendrimer generation, a control of intermolecular
