A blue light emitting element and the light emitting element, the blue light emitting element comprising: an electrode layer, a first metal layer, a second metal layer formed between the electrode layer and the first metal layer, and a second metal layer formed between the first metal layer and the second metal layer An organic material layer between the layers, the organic material layer includes a blue-shifted light-emitting layer, the peak of the first light-emitting spectrum of the blue-shifted light-emitting layer is shifted by the surface plasmon coupling between the first metal layer and the second metal layer to the peak of the second luminescence spectrum, wherein the peak of the first luminescence spectrum is from 490nm to 550nm, and the peak of the second luminescence spectrum is less than 510nm. In addition, a light-emitting element includes a first metal layer stacked in sequence, an organic material layer including a blue-shifted light-emitting layer, a second metal layer including a metal portion and an opening, an electrode layer, and a light-emitting layer doped with a dopant material , thereby emitting white light. |
