Compositions, optical component, system including an optical component, devices, and other products

A film comprising a carrier substrate including a predetermined arrangement of quantum confined semiconductor nanoparticles over a predetermined portion of a surface thereof, wherein at least a portion of the nanoparticles include a native ligand attached to a surface thereof, the ligand being represented by the formula:

• X-Sp-Z
• wherein:
• X represents a primary amine group, a secondary amine group, a urea, a thiourea, an amide group, a phosphonic acid group, or a phosphinic acid group;
• Sp represents a spacer group, such as a group capable of allowing a transfer of charge or an insulating group;
• and
• Z represents:
• (i) a reactive group capable of communicating specific chemical properties to the nanocrystal as well as provide specific chemical reactivity to the surface of the nanocrystal, and/or (ii) a group that is cyclic, halogenated, or polar a-protic, wherein the nanoparticles are included in a composition further including a host material and scatterers.

An ink composition comprising quantum confined semiconductor nanoparticles, scatterers, and a liquid vehicle, wherein the liquid vehicle comprises a composition including one or more functional groups that are capable of being cross-linked, wherein at least a portion of the nanoparticles include a native ligand attached to a surface thereof, the ligand being represented by the formula:

• X-Sp-Z
• wherein:
• X represents a primary amine group, a secondary amine group, a urea, a thiourea, an amide group, a phosphonic acid group, or a phosphinic acid group;
• Sp represents a spacer group, such as a group capable of allowing a transfer of charge or an insulating group;
