[0050] figure 1 It is a schematic structural diagram of the perovskite LED according to the first embodiment of the present disclosure. Please refer to figure 1 , the present disclosure is a perovskite LED containing an organic-inorganic hybrid perovskite single crystal light-emitting layer, comprising:
[0051] CH 3 NH 3 PbBr 3 Perovskite single crystal light-emitting layer 3;
[0052] The p-type hole transport layer 2 is formed on CH along the first direction 3 NH 3 PbBr 3 On the perovskite single crystal light-emitting layer;
[0053] A transparent conductive anode 1 formed on the p-type hole transport layer;
[0054] The n-type electron transport layer 4 is formed on CH along a second direction opposite to the first direction 3 NH 3 PbBr 3 On the perovskite single crystal light-emitting layer;
[0055] An electron injection layer 5 formed on the n-type electron transport layer; and
[0056] The metal electrode 6 is formed on the electron injection layer.
