In one aspect, structures (10) are provided that comprise a photonic crystal comprising a dielectric layer (14) comprising therein one or more light-emitting nanostructure materials(16). n In a further aspect, structures (10) are provided that comprise a dielectric layer (14) comprising first (16a) and second (16b) sets of light-emitting nanostructure materials (16a, b) at differing depths within the dielectric layer (14). |
