Abstract

The invention discloses a transparent organic electroluminescent device. The transparent organic electroluminescent device comprises a glass substrate, and a transparent anode, a cavity implantation layer, a cavity transmission layer, a green luminescent layer, an electron transmission layer, an electron injecting layer and a transparent cathode which are successively laminated on the glass substrate. The transparent anode comprises a hydroxysilane organic layer and a metal layer; the material of the hydroxysilane organic layer comes from at least one of (3-mercaptopropyl)trimethoxysilane, (3-mercaptoethyl)trimethoxysilane, (3-mercaptomethyl) trimethoxysilane and O,O,O-trimethyl-mercaptosilane; the material of the metal layer comes from at least one of a magnesium-silver alloy, a lithium-aluminum alloy, barium and calcium; and the material of the transparent cathode is indium tin oxide. According to the transparent organic electroluminescent device provided by the invention, the light emitting efficiency of an anode surface reaches more than 55% of the light emitting efficiency of a cathode surface, and the luminescence performance is excellent. The invention further discloses a preparation method of a transparent organic electroluminescent device.

Description

technical field

[0001] The invention belongs to the field of organic electroluminescence, and in particular relates to a transparent organic electroluminescence device and a preparation method thereof. Background technique

[0002] Organic electroluminescent devices (OLEDs) have some unique advantages: (1) OLEDs are diffuse surface light sources, and do not require an additional light guide system to obtain large-area white light sources like light-emitting diodes (LEDs); (2) Due to the diversity of organic light-emitting materials, OLED lighting can design the required color of light according to needs; (3) OLED can be made on a variety of substrates such as glass, ceramics, metals, plastics and other materials, which makes it easier to design lighting sources Freedom; (4) The OLED lighting panel is made by making OLED display, which can display information while lighting; (5) OLED can also be used as a controllable color in the lighting system, allowing users to adjust the...
