Title:
WAVELENGTH CONVERSION MATERIAL-CONTAINING SILICONE RESIN COMPOSITION, AND WAVELENGTH CONVERSION MATERIAL-CONTAINING SHEET
Document Type and Number:
WIPO Patent Application WO/2018/047757
Kind Code:
A1
Abstract:
Provided is a wavelength conversion material-containing composition that is capable of suppressing precipitation of the wavelength conversion material, and when applied as the wavelength conversion material of a semiconductor light-emitting device, is capable of suppressing a decline in the light output of the semiconductor light-emitting device and achieving high light output. A wavelength conversion material-containing silicone resin composition that includes a wavelength conversion material, a catalyst, and a silicone resin, wherein: the silicone resin content is 5 mass% or more; the silicone resin substantially comprises a condensate silicone resin, and includes a structural unit represented by formula (A3); the wavelength conversion material content is 20 mass% or more; the wavelength conversion material-containing silicone resin composition does not substantially include silica particles; and the wavelength conversion material-containing silicone resin composition is a liquid composition having a viscosity of 1,000-500,000 mPa⋅s at 25°C. (In the formula, R1 represents an alkyl group or an aryl group.)
