Abstract
The utility model provides a yellow organic electroluminescent device, which particularly relates to an organic luminescent device based on exciplex shining and pertains to the technical field of organic electroluminescent display. A cavity transmission layers is added between red organic salt luminescent material and the anode of the luminescent device, which are distributed in a layer shape. The luminescent device is characterized in that a cathode is connected with an organic salt layer which is connected with the cavity transmission layer; the cavity transmission layer is connected with the anode which is connected with a substrate. As the technical proposal is adopted, the yellow organic electroluminescent device has the advantages of avoiding the direct influence on the position of spectrum peak value of the electroluminescent device due to different dosage concentration is prevented, thus having a fixed yellow luminescent spectrum peak value and simple technique.
Description
Technical field
The utility model relates to a kind of yellow organic electroluminescence device, relates in particular to a kind ofly based on the luminous organic luminescent device of exciplex, belongs to the Display Technique field of organic electroluminescent.
Technical background
At first reported since people such as C.W.Tang in 1987 since the organic electroluminescence device of higher luminosity and luminous efficiency, low driving voltage, numerous researchers of being engaged in this respect research have been done a large amount of work, and its corresponding luminescence mechanism has also been done further investigation.But single layer structure device for the luminous organic material preparation, often its luminosity and luminous efficiency are not high, need in device, introduce hole transmission layer and electron transfer layer improves its luminescent properties, but the introducing of transport layer, may make two organic materials form exciplex at the interface, and make device launch the color of light that exciplex sends.The realization of yellow organic electroluminescence device generally is the organic fluorescence materials of coloured light of turning to be yellow by mixing, utilize matrix to realize that to the energy delivery of dopant material sodium yellow shows, and the difference of doping content can directly influence the position of device electroluminescent spectrum peak value.
Summary of the invention
The purpose of this utility model is to provide based on the luminous a kind of yellow organic electroluminescence device of exciplex, and what device sent is sodium yellow.
For achieving the above object, this luminescent device is to have added one deck hole transmission layer at red organic salt luminescent material with between the anode, and be layered arrangement, it is characterized in that: negative electrode links to each other with organic salt deposit, organic salt deposit links to each other with hole transmission layer, hole transmission layer links to each other with anode, and anode links to each other with substrate.Substrate is a glass, and anode is the ITO transparency conducting layer, and hole transmission layer is TPD, and organic salt deposit is red organic salt luminescent material, and negative electrode is metallic aluminium or magnesium silver alloy.
Because adopt technique scheme, the advantage that is had with good effect is: avoided because the different direct influences to device electroluminescent spectrum peak of doping content have fixing Yellow luminous spectrum peak, technology is simple.
