Title (EN) ORGANIC LIGHT-EMITTING DEVICE
(FR) DISPOSITIF D’ÉMISSION DE LUMIÈRE ORGANIQUE
Abstract:
(EN) An organic white light-emitting device comprising an anode, a cathode and at least one light- emitting layer between the anode and the cathode, wherein a first light-emitting layer comprises a first light-emitting compound of formula (I): wherein R1, R2 and R3 independently in each occurrence is a substituent; M1 is a transition metal; L1 is a ligand other than a ligand of formula: (II) a and b are each 0 or a positive integer; x is at least 1; and y is 0 or a positive integer, a light- emitting layer of the device comprising at least one further light-emitting material.
(FR) La présente invention concerne un dispositif d’émission de lumière blanche organique comprenant une anode, une cathode et au moins une couche d’émission de lumière entre l’anode et la cathode, une première couche d’émission de lumière comprenant un premier composé d’émission de lumière de la formule (I) : où R1, R2 et R3 indépendamment dans chaque occurrence est un substituant ; M1 est un métal de transition ; L1 est un ligand autre qu’un ligand de la formule : (II) ; a et b sont chacun 0 ou un nombre entier positif ; x est au moins 1 ; et y est 0 ou un nombre entier positif, une couche d’émission de lumière du dispositif comprenant au moins un autre matériau d’émission de lumière.
