LIGHT-EMITTING DEVICE COMPRISING PEROVSKITE-ORGANIC SMALL MOLECULE HOST MIXED LIGHT-EMITTING LAYER AND METHOD OF MANUFACTURING SAME

摘要

The present invention relates to a light-emitting device comprising a perovskite-organic small molecule host mixed light-emitting layer and a method for manufacturing same. According to the present invention, it is possible to adjust an energy level, a charge transport rate, and a light-emission wavelength of the perovskite-organic small molecule host mixed light-emitting layer in the light-emitting device according to a material type, a ratio between materials, and a deposition rate by using a deposition method. In addition, there is an advantage of it being possible to improve electroluminescence efficiency by controlling an electron-hole recombination zone of the light-emitting device through same. Moreover, there is an advantage of it being possible to reduce the size of a perovskite crystal formed by co-depositing an organic small molecule host with a metal halide perovskite.
