BASF and OSRAM developed a 60 lm/W all-phosphorescent OLED lighting panel

BASF and Osram Opto Semiconductors have developed a highly efficient white OLED panel. The efficiency is over 60 lm/w. This development was part of the OPAL project which launched in 2008. Other partners in this project include AixtronPhilips and Applied Materials.

The new OLED panel contains phosphorescent emitters - including a new emitter. It suffers from short lifetime, and now the companies will work on extending the lifetime of those emitters, especially the blue one. BASF says they have started developing blue phosphorescent emitters as early as 2013, and these are based on an iridium complex.
