Abstract:
A light-emitting device comprises first and second dot members. The first dot member is formed so that it makes contact with the second dot member. The first dot member comprises a plurality of first quantum dot layers. Each of the plurality of first quantum dot layers comprises a plurality of first quantum dots and a silicon dioxide film. The first quantum dot comprises an n-type silicon dot. The second dot member comprises a plurality of second quantum dot layers. Each of the plurality of second quantum dot layers comprises a plurality of second quantum dots and a silicon dioxide film. The second quantum dot comprises a p-type silicon dot.
