MATERIAL FOR ORGANIC ELECTROLUMINESCENCE DEVICE AND METHOD FOR PRODUCING THE SAME

Abstract: A material adapted for an organic electroluminescence device and having a radiative recombination center is produced by bringing a source (1) containing a radiative recombination center formig compound capable of absorbing laser light into contact with a target (2) transmitting laser light and having at least one of an electron transport function and a hole transport function, irradiating the surface on the source (1) side (or on the target (2) side) with a laser beam the intensity of which is less than the laser ablation threshold of the source (1), and injecting a radiative recombination center forming compound (3) in the source (1) into the target (2). Thus, the material can be subjected to fine patterning.
