  Electric field-modulated photoluminescence (EML) was measured in vacuum-evaporated films of bathocuproine (BCP), electron-transporting material commonly used in organic light-emitting diodes (OLEDs). The external electric field of 106 V/cm strength decreases long-wavelength photoluminescence (PL) up to 10% but the same effect on short-wavelength PL is above one order of magnitude smaller. The distinctive difference between the...

  Metodą elektroabsorpcji (EA) badano stany wzbudzenia elektronowego w próżniowo naparowanych warstwach diamin (TPD, TAPC) i dendrymeru aminowego m-MTDATA. Widma EA amin złożonych porównano z widmem monomeru trifenylaminy (TPA). Kształt widm EA świadczy o obecności zdegenerowanych i quasi-zdegenerowanych stanów elektronowych.
