Blue light organic electroluminescent layer, blue light organic electroluminescent device and display device

The invention discloses a blue light organic electroluminescent layer, a blue light organic electroluminescent device and a display device. The blue light organic electroluminescent layer structurally comprises a main body which is formed by mixing a p-type material and an n-type material, and a sensitizer and an emitter which are doped in the main body; wherein the sensitizer is selected from a phenyl derivative modified heteroleptic iridium (III) complex, and the emitter is selected from a boron-containing derivative. According to the scheme, the problems of low efficiency and short service life of a blue light organic light emitting diode device are well solved. 本发明公开一种蓝光有机电致发光层、蓝光有机电致发光器件及显示装置。所述蓝光有机电致发光层结构中包含：主体，由p型材料和n型材料混合形成，以及掺杂在所述主体中的敏化剂和发射体；其中，所述敏化剂选自苯基衍生物修饰的杂配铱(III)配合物，所述发射体选自含硼衍生物。该方案很好地解决了蓝光有机发光二极管器件效率低和寿命短的问题。
