1. An ink, comprising:
a siloxane polymer having at least 13 mol. % diphenylsiloxane content relative to the total mol. % of the siloxane polymer; and
a filler, wherein the siloxane polymer has a defined diphenyl content predetermined to cause a refractive index of the siloxane polymer to be within about 5% of a refractive index of the filler.
