Abstract
An organic electroluminescence device material having emission centers is formed by bringing a source ( ) containing an emission center-forming compound absorptive of laser beams into contact with a target ( ) having at least one function selected from an electron-transporting function and a hole-transporting function, and irradiating a laser beam at an intensity of or below the ablation threshold value of the source ( ) from the source ( ) side (or the target ( ) side) thereby to implant the emission center-forming compound ( ) of the source ( ) into the target ( ). Thus, it is possible to make a fine and minute pattern on the organic electroluminescence device material.
