Claim 9:
10. A photocured composition comprising:
a polymer matrix formed from one or more monomers;
a blue photoluminescent material mixed in the polymer matrix, the blue photoluminescent material 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 with an emission peak in a range of about 420 nm to about 480 nm, wherein 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%, and wherein the blue photoluminescent material is an organic material or an organometallic material; and
components of a photoinitiator that initiated polymerization to form the polymer matrix.
