Embodiment 1

[0031] Such as figure 1 , figure 2 As shown, a luminescent aluminum plate includes an aluminum substrate 1 (as a cathode), a small area of ​​one side of the aluminum substrate 1 is oxidized to form a layer of aluminum oxide layer 2, and the outer 2 / 3 area of ​​the aluminum oxide layer 2 is coated with a A thin aluminum layer 3 (as an anode), a layer of LiF layer 4 is coated on the remaining area of ​​the other side of the aluminum substrate 1, and the narrow U-shaped side of the aluminum substrate 1 is exposed, and the aluminum substrate 1 is located between the U-shaped sides The inner part (that is, the area where the LiF layer 4 and other functional layer coatings are located) is separated from the thin aluminum layer 3 by the remaining 1 / 3 area of ​​the inner side of the aluminum oxide layer 2 . Other functional layer coatings specifically refer to a layer of Alq coated on the LiF layer 4 3 Layer 5, Alq 3 A layer of Alq plated on layer 5 3 :C 5457 6th Floor 6, Alq 3...

Embodiment 2

[0041] The light-emitting plate structure is Al / LiF / Alq 3 / NPB / MoO 3 / Al / SiO 2 , the color is still yellow-green, and the light effect is 1.3cd / A.

[0042] According to analysis and calculation, the luminous efficiency of the light-emitting panel in Example 1 is significantly better than that in Example 2.

Abstract

The invention provides a light-emitting plate and a preparation method thereof. A small-area part of one side of an aluminum substrate is oxidized and an aluminum oxide layer is formed. After that, 2 / 3 part of the aluminum oxide layer is plated with a thin aluminum layer, while a narrow U-shaped edge is reserved on the remaining part of the aluminum substrate. A LiF layer is plated inside U-shapededge, and an Alq3 layer is plated on the LiF layer. An Alq3:C5457 layer is plated on the Alq3 layer. An NPB layer is plated on the Alq3:C5457 layer. A MoO3 layer is plated on the NPB layer. An aluminum film is plated on the MoO3 layer. Therefore, the aluminum film is plated on the MoO3 layer and also covers the aluminum oxide layer to be connected with the thin aluminum layer. Finally, a SiO2 layer is plated on the aluminum film, so that the light-emitting plate is formed. The light-emitting plate can be applied to the aspects of urban lighting, decorative lighting and the like.

Description

technical field [0001] The invention relates to the fields of city lighting and decorative lighting, in particular to a luminescent aluminum plate. Background technique [0002] The lighting project, also known as the urban glory project, refers to the lighting of shopping malls, tourist attractions, streets and other places with a lot of traffic in order to beautify the urban environment and improve the overall image of the city. The construction of the lighting project makes the city have a strong sense of the times, the streets become spectacular, and the business opportunities of the commercial street are promoted. [0003] In recent years, various city governments have attached great importance to urban lighting work, and have carried out urban lighting construction to varying degrees, taking the construction of urban lighting projects as an important measure to improve and beautify the urban environment. At present, the urban lighting project has achieved unprecedente...
