Abstract
A solid light-emitting device comprising a light-emitting semiconductor element and a phosphor dispersed in a sealant, in which the phosphor is exited by the light emitted by the semiconductor element to emit a visible light of a wavelength differing from that of the light emitted by the semiconductor element and is a silicate phosphor or a phosphor having a hydroxyl group on its surface, and the sealant is a condensation product of a prepolymer produced by condensation of polydimethyl-siloxane having a silanol group at both ends and an oligomer of an alkoxide of a metal or a semimetal or its derivative.
