OG exemplary drawing
 
1. A print material, comprising:
a curable material;
scattering particles;
quantum dots;
a first polymerization initiator; and
a second polymerization initiator, wherein during a first curing process the first polymerization initiator has a higher decomposition rate than the second polymerization initiator, and during a second curing process the second polymerization initiator has a higher decomposition rate than the first polymerization initiator.
 
10. A cured print material comprising a product of curing a print material that comprises:
a curable material;
scattering particles;
quantum dots;
a first polymerization initiator; and
a second polymerization initiator, wherein during a first curing process the first polymerization initiator has a higher decomposition rate than the second polymerization initiator, and during a second curing process the second polymerization initiator has a higher decomposition rate than the first polymerization initiator.
 
19. A cured print material comprising a product of curing a print material using a photo-curing process and a thermal curing process, the print material comprising:
a curable material;
a scattering material;
quantum dots;
a first polymerization initiator; and
a second polymerization initiator, wherein during the photo-curing process the first polymerization initiator has a higher decomposition rate than the second polymerization initiator, and during the thermal curing process the second polymerization initiator has a higher decomposition rate than the first polymerization initiator.
