- Abstract
- Light emission in phosphorescent quantum well structure which can confine excitons within an
emitting layer was investigated. A multilayer quantum well structure which has a narrow triplet band
gap host material sandwiched between wide triplet band gap host materials was designed, and
device performances were studied. The multilayer emitting structure gave high efficiency of
47 cd/A compared with 11 cd/A of standard green devices.
