[Analysis Case] Evaluation of Layer Structure of Organic EL Devices

Preventing oxidation degradation during cutting processing under N2 atmosphere.

Organic EL devices are prone to degradation in the atmosphere, so processing under an N2 atmosphere is necessary. We present the measurement results of Alq3 for organic EL devices that were machined in an N2 atmosphere and left in the atmosphere for 30 minutes, compared to those that were not exposed to the atmosphere. When left in the atmosphere, there is a strong tendency for peaks associated with oxygen to appear in Alq3. In the N2 atmosphere, there is a strong tendency for the parent ions of Alq3 to be observed. By avoiding exposure to the atmosphere, results closer to the true state can be obtained.
