  • Patent number: 11787943
    Abstract: A curable silicone composition is provided. The curable silicone composition is useful for forming a cured product which inhibits the discoloration of silver electrodes or a silver-plated substrate in an optical semiconductor device due to a sulfur-containing gas. The curable silicone composition comprises at least one type of a crown compound. An optical semiconductor device is also provided. The optical semiconductor device has excellent reliability after a sulfur resistance test, in which an optical semiconductor device on silver electrodes or a silver-plated substrate is sealed, covered, or adhered with a cured product of the curable silicone composition.
