FIELD: physics, optics.
SUBSTANCE: invention relates to solid-state light sources built around organic LEDs. Organic LED with white emission spectrum comprises translucent substrate with translucent anode ply and cathode metal ply and light-emitting ply located there between. Note here that the latter comprises low-molecular polyvinylcarbazole, 2-(4-xenyl)-5-(4-tret-buthylphenyl)-1,3,4-oxadiazol and branched oligoarylsilane of presented formula. Diode can have the following extra plies: injection of holes, electron blocking ply, hole blocking ply and electron injection ply.
EFFECT: expanded range of organic LEDs, enhanced performances and range of 35-750 nm.
