| Popis: | Excitation wavelength dependent emission maximum (400 - 560 nm) of a room temperature ionic liquid has been investigated employing time-resolved fluorescence anisotropy based rotational dynamical analyses. Employing Stokes-Einstein-Debye relationship we could show that nano-aggregate having aggregation volume of ∼250 A3, ∼350 A3, ∼400 A3 and ∼500 A3 emit at ∼400 nm, ∼450 nm, ∼500 nm, and ∼560 nm respectively.
