Original Abstract Submitted

A display includes a light emitting diode and a color conversion layer that includes a polymer matrix, a blue photoluminescent material, and a components of a photoinitiator that initiated polymerization to form the polymer matrix. The blue photoluminescent material is selected to absorb ultraviolet light with a maximum wavelength in a range of about 300 nm to about 430 nm and to emit blue light. The blue photoluminescent material also has an emission peak in a range of about 420 nm to about 480 nm. The full width at half maximum of the emission peak is less than 100 nm, and the photoluminescence quantum yield is in a range of 5% to 100%.
