The efficiency of polymer light‐emitting diodes (LEDs) is highly dependent on the heat treatment conditions and procedures. With the aim of enhancing the luminescence efficiency of polymer LEDs, the effect of thermal annealing at temperatures above the T g of the emissive polymer in a ITO/polymer/Al device is investigated. Four different cases are considered: an unannealed device, a pre‐ (aluminum) deposition annealed device, a post‐deposition annealed device, and a post‐deposition annealed device after pre‐deposition annealing.
