Since the light emitting layer inside the organic EL is made of an organic substance that is sensitive to oxidation and moisture, it has a drawback that the light emitting life is short. Therefore, we try to improve the deterioration by producing a hybrid fluorescent thin film in which the organic light emitting material is covered with an inorganic material (SiO₂) having oxidation resistance and water resistance. In particular, the purpose of this study is to further improve deterioration by covalently bonding a luminescent polymer (organic) having a vinyl group and a silane coupling agent (inorganic) by a radical reaction to improve dispersibility.
