Title:
COATED KSF PHOSPHOR, METHOD FOR PRODUCING SAME, CURABLE SILICONE COMPOSITION CONTAINING SAME, AND OPTO-SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/037831
Kind Code:
A1
Abstract:
The present invention pertains to a coated KSF phosphor particle, said coated KSF phosphor particle having a surface coating with a polymer, characterized in that the polymer is a (meth)acrylic acid ester polymer and the ratio of the polymer to the total coated KSF phosphor particle is in the range of 0.1-20 mass%. Thus, provided are a KSF phosphor particle showing suppressed generation of an acidic substance even under high temperature conditions, and a curable silicone composition containing the phosphor particle.
