We achieved a highly efficient white organic light emitting diode with a single emitting layer consisting of three kinds of dopants. The emitting layer was fabricated with a one‐step solution coating process. A maximum power efficiency of 70 lm/W was obtained by applying high photoluminescent quantum yield dopants and improving light‐extraction efficiency.
