Title:
CURED PRODUCT, WAVELENGTH CONVERSION SHEET, LIGHT-EMITTING DEVICE, SEALING MEMBER, AND SEMICONDUCTOR LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/047760
Kind Code:
A1
Abstract:
The invention provides a cured product having high hardness, high crack-resistance, and high heat-resistance, simultaneously. The cured product contains a condensation-type silicone resin cured product and satisfies (1) and (2). (1) In a solid 29Si-nuclear magnetic resonance spectrum of the condensation-type silicone resin cured product, a peak attributable to a T-body silicon atom (silicon atom bonded to three oxygen atoms) is present. (2) The non-uniform domain size is 50 Å or greater (value obtained by: impregnating with tetrahydrofuran and thereby causing a swelling of the condensation-type silicone resin cured product; plotting a graph of the small-angle X-ray scattering measurement values for this sample, with the X-ray wavenumber on the horizontal axis, and the scattering intensities comprising the measured scattering intensities minus the blank scattering on the vertical axis; and fitting the graph with formula (A)).
(In the formula, ξ represents the network mesh size, Ξ represents the non-uniform domain size, I(q) represents the scattering intensity, q represents the wavenumber, A and B represent fitting constants).
