1. A polymer dot comprising:
A condensed chromophoric polymer comprising a narrow-band monomer and one or more general monomers wherein the narrow-band monomer is integrated into the chromophoric polymer, the condensed chromophoric polymer having an emission spectrum with a full width half maximum (FWHM) of 5 nm to 70 nm,
wherein a ratio of a number of the narrow-band monomer to the general monomers is 1:20 to 1:1000; and wherein the general monomers comprise energy donors and the narrow-band monomer is an energy acceptor configured to receive energy from one or more of the general monomers,
wherein the polymer dot is a sub-micron sized particle,
wherein the condensed chromophoric polymer is collapsed or packed in the sub-micron sized particle,
wherein the chromophoric polymer is a semiconducting polymer,
wherein the narrow-band monomer is selected from the group consisting of a BODIPY monomer, a BODIPY derivative monomer, a squaraine monomer, a squaraine derivative monomer, a metal complex monomer, a metal complex derivative monomer, a porphyrin monomer, and a porphyrin derivative monomer, and
wherein the general monomers are selected from the group consisting of: fluorene, a fluorene derivative, phenylene vinylene, a phenylene vinylene derivative, phenylene, a phenylene derivative, benzothiadiazole, a benzothiadiazole derivative, thiophene, a thiophene derivative, carbazole fluorene, and a carbazole fluorene derivative.
