Abstract
In a radiation or high energy particle responsive system useful as a scintillator, and comprising, PA0 a first component which interacts with said radiation or high energy particle to emit photons in a certain first wavelength range; and PA0 at least one additional solute component which absorbs the photons in said first wavelength range and thereupon emits photons in another wavelength range higher than said first range; PA0 an improvement is provided wherein at least one of said components absorbs substantially no photons in said wavelength range in which it emits photons, due to a large Stokes shift caused by an excited state intramolecular rearrangement.
