SEALING MATERIAL FOR DEEP ULTRAVIOLET LIGHT, DEEP ULTRAVIOLET LIGHT EMITTING DEVICE AND METHOD FOR PRODUCING DEEP ULTRAVIOLET LIGHT EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a sealing material for deep ultraviolet light and a deep ultraviolet light emitting device.;SOLUTION: A sealing material for deep ultraviolet light is predominantly composed of polyorganosiloxane in which a ratio of the number of carbon-carbon bonds to the number of Si atoms is 5% or less. A side chain of the polyorganosiloxane is a methyl group or a trimethylsilyloxy group.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
