    摘要: Preparation of a solid fluorescent composition comprising (1) mixing a host chromophore and an effective amount of a pigment precursor in a solvent, then generating a pigment as guest chromophore in-situ from the pigment precursor, and, subsequently, isolating the mixture of the host and guest chromophores, thereby forming a solid solution, or (2) mixing a polymer as a matrix or a polymer precursor and a pigment precursor in a solvent, if desired in the presence of a chromophore being a host component, then generating a pigment in-situ from the pigment precursor (being the guest component if a host component is present), and, subsequently, isolating the mixture of polymer and pigment, and—if present—the host component, thereby forming a solid solution, wherein in all cases where there is a host component, the absorption spectrum of the pigment (guest chromophore) overlaps with the fluorescence emission spectrum of the host chromophore.
