LIGHT-EMITTING DEVICE ARRANGED BY USE OF SILVER NANOPARTICLES, AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting device with a circuit pattern which has a glossy surface and is superior in electrically conducting property and thermally conducting property without the need for plating or etching; and a manufacturing method by which such a light-emitting device can be obtained with stability simply and conveniently without thermally damaging an optical semiconductor element.SOLUTION: Provided are a light-emitting device and a manufacturing method thereof. The light-emitting device comprises: an optical semiconductor element 1; a circuit pattern 2; and an insulative substrate 4. In the light-emitting device, the optical semiconductor element 1 is electrically and/or thermally connected with the circuit pattern 2; the circuit pattern 2 is provided on the insulative substrate 4; the circuit pattern 2 is formed by baking a composition 3 including silver nanoparticles; and the silver nanoparticles are produced as a result of a thermal decomposition of a mixture containing an amine (A) having an aliphatic hydrocarbon group and an amino group, and a silver compound (B).SELECTED DRAWING: Figure 1
