Korean Kongkae Taeho Kongbo KR 2002068713 A 28 Aug 2002, No pp. given (Korean). (Korea, Republic Of). CODEN: KRXXA7. CLASS: ICM: C09K011-06. APPLICATION: KR 2001-8955 22 Feb 2001. DOCUMENT TYPE: Patent CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Section cross-reference(s): 74 An org. light emitting device using bis(10-hydroxybenzoquinolinato)beryllium and bis(2-Me-8-hydroxyquinolinato)beryllium mixt. as a light emitting material and its prepn. method are provided, to allow it to be driven at a low voltage and to improve the luminous efficiency and the brightness at a low voltage. 148896-39-3 and 18747-41-6 are cas registry numbers of chemicals which are used as reagents here. The org. light emitting device comprises at least one active layer on a substrate, and a light emitting layer which is one among the active layers comprises bis(10-hydroxybenzoquinolinato)beryllium and bis(2-Me-8-hydroxyquinolinato)beryllium in the mass ratio of 1:5 to 5:1. Preferably the mass ratio is 3:1. The light emitting layer also acts as an electron transfer layer. The light emitting layer is prepd. by depositing bis(10-hydroxybenzoquinolinato)beryllium and bis(2-Me-8-hydroxyquinolinato)beryllium by org. mol. deposition. .
