MATERIAL FOR ORGANIC ELECTROLUMINESCENCE DEVICE AND ITS MANUFACTURING METHOD

摘要

A process for producing for a material for an organic electroluminescent device having an emission center comprises irradiating a laser beam to implant an emission center-forming compound 3 constituting a source 1 into a target 2 having at least one function selected from an electron-transporting function and a hole-transporting function. According to the process, the laser beam and at least the target are relatively moved with irradiating the beam to form the emission center with a predetermined pattern. Moreover, the source and the target being in contact with each other may be moved relative to the laser beam for forming the emission center with a predetermined pattern. Further, the emission center at an area, corresponding to an interference pattern of an interference light, of the target may be formed by irradiating the interference light of the laser beam. <IMAGE>
