A curable silicone composition includes (A) a polydiorganosiloxane having an average, per molecule, of at least two aliphatically unsaturated organic groups and at least one aromatic group; (B) a branched polyorganosiloxane having an average, per molecule, of at least one aliphatically unsaturated organic group and at least one aromatic group; (C) a polyorganohydrogensiloxane having an average per molecule of at least two silicon-bonded hydrogen atoms and at least one aromatic group, (D) a hydrosilylation catalyst, and (E) a silylated acetylenic inhibitor. The curable silicone composition cures to form a cured silicone resin having a refractive index > 1.40. The curable silicone composition cures by heating to form a cured silicone resin with an optical transparency > 95% at a thickness of 2.0 mm or less at 400 nm wavelength after thermal aging by heating at 200 °C for 14 days. |
