Abstract
Provided is a light-emitting diode and a method for preparing the same. The light-emitting diode includes an anode, a hole transport layer, a perovskite light-emitting layer, an electron transport layer and a cathode stacked in sequence, in which the perovskite light-emitting layer includes a first sublayer and a second sublayer stacked in sequence, with a material for forming the first sublayer including an inorganic perovskite material, and with a material for forming the second sublayer being an organic perovskite material.
