Abstract

See full text

The present disclosure discloses a film layer analysis method for an electroluminescent device. The electroluminescent device includes an anode layer, an electroluminescent material layer, and a silver-bearing cathode layer that are sequentially laminated. The film layer analysis method includes stripping the silver-bearing cathode layer from the electroluminescent device by using a first ion sputtering source to obtain an analysis sample with the electroluminescent material layer exposed, and analyzing the exposed electroluminescent material layer by using a second ion sputtering source; wherein sputtering energy of the first ion sputtering source is greater than sputtering energy of the second ion sputtering source.
