ELECTROLUMINESCENT ELEMENT DESIGN METHOD, ELECTROLUMINESCENT ELEMENT MANUFACTURED USING SUCH DESIGN METHOD, AND ELECTROLUMINESCENT ELEMENT MANUFACTURING METHOD USING SUCH DESIGN METHOD

摘要

This electroluminescent element design method includes the following: preparing a reference element provided with the configuration of a electroluminescent element, and a desired analysis element provided with the configuration of the electroluminescent element; carrying out quantum optics analysis, magnetic field analysis, and light-ray tracking, using as the design variables the thickness and complex relative permittivity of each of a first transparent member, a first electrode, a first functional layer, a second functional layer, a photon generation layer, and a second electrode, and using the positions of light emission points in the photo generation layer and the distribution of the light emission points in the photo generation layer; calculating, in both the reference element and the analysis element, the efficiency of light extraction from the photon generation layer to the transparent member or the air, and thereby computing a "light extraction efficiency ratio" between the reference element and the analysis element; finding the thickness of the layers which constitute the reference element and the analysis element and finding the relationship between the complex relative permittivity of each layer and the "light extraction efficiency ratio"; and on the basis of the foregoing relationship and air measured by flowing current in the reference element or the electroluminescence spectrum in the first transparent member, obtaining the thickness and complex relative permittivity of each of the first transparent member, the first electrode, the first functional layer, the second functional layer, the photon generation layer, and the second electrode, which are used as the design variables.
