Provided are light-emitting devices and methods for making and using the same. The light-emitting device comprises: a transparent substrate ( 101 ), a light-extracting polymer layer ( 102 ) having one or more elevated regions ( 104 ) distributed on a surface of the light-extracting polymer layer ( 102 ) facing away from the transparent substrate ( 101 ), a first electrode layer, wherein the light-extracting polymer layer ( 102 ) is disposed between the first electrode layer and the transparent substrate ( 101 ), a second electrode layer and a light-emitting layer disposed between the first electrode layer and the second electrode layer, wherein the light-emitting layer is configured to emit light when voltage is applied between the first electrode and the second electrode layer. |
