A composition includes an organopolysiloxane component (A) comprising at least one of a disiloxane, a trisiloxane, and a tetrasiloxane, and has an average of at least two alkenyl groups per molecule. The composition further includes an organohydrogensiloxane component (B) having an average of at least two silicon-bonded hydrogen atoms per molecule. Components (A) and (B) each independently have at least one of an alkyl group and an aryl group and each independently have a number average molecular weight less than or equal to 1500 (g/mole). The composition yet further includes a catalytic amount of a hydrosilylation catalyst component (C), and titanium dioxide (TiO2) nanoparticles (D). The composition has a molar ratio of alkyl groups to aryl groups ranging from 1:0.25 to 1:3.0. A product of the present invention is the reaction product of the composition, which may be used to make a light emitting diode. |
