Abstract:
1. A phosphor-containing sheet having a storage modulus of 0.1 MPa or more at 25° C. and a storage modulus of less than 0.1 MPa at 100° C., wherein a resin main, component of the phosphor-containing sheet is a crosslinked product formed by subjecting a crosslinkable silicone composition containing at least the following compositions (A) to (D) to a hydrosilylation reaction; (A) organopolysiloxane represented by an average unit formula: in which R (B) organopolysiloxane, 5 to 15 parts by weight with respect to 100 parts by weight of the component (A), represented by the general formula: in which R (C) organotrisiloxane, in such an amount that a molar ratio of a hydrogen atom coupled with a silicon atom in this component to the total of the alkenyl group in the component (A) and the component (B) is 0.5 to 2, represented by the general formula: in which R (D) a catalyst for a hydrosilylation reaction, in such an amount sufficient to promote a hydrosilylation reaction of the alkenyl groups in the component (A) and the component (B) with the hydrogen atom coupled with a silicon atom in the component (C).
