This study examines the effects of the thickness and structure of a silver (Ag) interlayer on the performance of phosphorescent red-emitting transparent organic light-emitting diodes (TOLEDs). Inserting an Ag interlayer enabled the top emission of TOLEDs to be enhanced by 1.4–3.1, resulting in a ten-fold decrease in bottom-to-top ratios from 7.6 to 0.76. We show that an extra thin Ag interlayer with a carefully constructed structure could optimize TOLEDs’ top emission by altering their microcavities. The top emission enhancement was verified by comparing the forward emission of devices with and without Ag interlayers. Thus, the TOLEDs with Ag interlayers displayed more balanced light emissions.
