Title:
LIGHT-EMITTING DIODE PACKAGE STRUCTURE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2020145240
Kind Code:
A
Abstract:
To provide an improved white LED and a method for manufacturing the same.SOLUTION: An LED package structure 100 includes a substrate 102 and a light-emitting unit 104 disposed on the substrate. The light-emitting unit includes a gallium nitride semiconductor 1042 and a polymer layer 1046 containing the gallium nitride semiconductor. The polymer layer includes resin and at least one compound fluorescent gold nanocluster 110 dispersed in the polymer. Each compound fluorescent gold nanocluster includes a gold nanocluster 1110, and a capping layer 1120 containing at least a part of an outer surface of the gold nanocluster. The capping layer includes a matrix 1122 formed of a benzene compound, and a plurality of phosphine compounds 1124 distributed in the matrix.SELECTED DRAWING: Figure 1
