← TechnologyWhich outcome occurs when an organic LED's (OLED) cathode oxidizes?
A)Reduced light emission efficiency✓
B)Improved color rendering index
C)Increased forward voltage stability
D)Enhanced thermal dissipation rate
💡 Explanation
Oxidation increases cathode resistance with a quenching effect. This is due to the increased energy barrier experienced by electrons during electron injection, therefore reducing the electroluminescence efficiency rather than any other property since oxidation inhibits electron flow.
