A part of the absorbance of infrared radiation of which wave number is in the range of 830 to 900 cm−1 is less than both the absorbance of infrared radiation at the wave number of 830 cm−1 and the absorbance of infrared radiation at the wave number of 900 cm−1 when the insulating film to which an electric field has never been applied is measured by means of Fourier Transform Infrared Spectroscopy at room temperature.

摘要:
In an organic EL device, when a voltage is applied across an anode and a cathode, holes are moved in a hole transport layer and electrons are moved in an electron transport layer, and the holes and the electrons are recombined in a light emitting layer. In the light emitting layer, excitons are produced by energy released upon the recombination, and the excitons release energy in the form of fluorescence or phosphorescence or emit light when returning to the ground state. The hole transport material is used in the hole transport layer, in which the amount of cationic impurities and/or the amount of anionic impurities are controlled to be small, so that the decrease of light-emission luminance of the organic EL device is suppressed and excellent light emitting properties are maintained for a long period of time.

Techniques for predicting the behavior of dopant and defect components in a substrate lattice formed from a substrate material can be implemented in hardware or software. Fundamental data for a set of microscopic processes that can occur during one or more material processing operations is obtained. Such data can include data representing the kinetics of processes in the set of microscopic processes and the energetics and structure of possible states in the material processing operations. From the fundamental data and a set of external conditions, distributions of dopant and defect components in the substrate lattice are predicted. The distributions of one or more fast components are each predicted by calculating the concentration of the particular fast component for a time period before that fast component reaches its pseudo steady state by solving a first relationship and calculating the concentration of that fast component after the time period by solving a second relationship based on other components, the pseudo steady state of a fast component being a state in which the concentration of that fast component is determined by concentrations of other components. The distribution of Bs3Bi, in addition to the distributions of Bs, BsI, BsI2, BsI3, BsBi, BsBi2, BsBi3, BsBiI, BsBiI2, Bs2Bi, Bs2Bi2, I and In, are calculated by solving the first relationship to predict the distribution of boron after annealing, where Bs and Bi represent substitutional boron and interstitial boron, respectively, and I and In represent interstitial silicon and a cluster of n I's, respectively.

A light emitting material is used to form the light emitting layer 42. When the light emitting layer 42 is formed using the light emitting material, the light emitting layer contains one or more kinds of metallic impurities, but an amount of a metallic impurity of which content is the largest among the metallic impurities contained in the layer is 2.5 ppm or less, or when the light emitting material is dissolved in a liquid so that the concentration thereof becomes 2.0 wt %, the liquid contains one or more kinds of metallic impurities, but an amount of the metallic impurity of which content is the largest among the metallic impurities contained in the liquid is 50 ppb or less. By using such a light emitting material, the decrease of light-emission luminance of the organic EL device 1 can be suppressed.
