Abstract

Tunable, multiple emission is exhibited by nanoparticles of 1,3-diphenyl-5-pyrenyl-2-pyrazoline (DPP; see picture), which ranges from near-UV to green. Tuning could be effected by alteration of either the excitation wavelength or the nanoparticle size. In contrast, DPP in dilute solution only showed the emission characteristics of the pyrene chromophore. In bulk crystals, only the emission characteristics of the pyrazoline chromophore were exhibited.
