In this Accepted 31 July 2017 contribution, we synthesized a conjugated polymer which integrates blue-, green- and red-emitting Available online 4 August 2017 components into the backbone in an appropriate molar ratio. After being transferred from solution to nanoparticles, its ﬂuorescence color turns from blue to pink with enhanced ﬂuorescence quantum yield. Keywords: After incorporation of an amphiphilic polymer as matrix, white-emissive polymer nanoparticles are ﬂuorescence obtained as a result of optimized energy transfer degree among the
