Since the light emitting layer inside the organic EL is made of an organic substance that is sensitive to oxidation, it has the disadvantage of having a short light emitting life. Therefore, in this research, we try to improve the deterioration by synthesizing an oxidation-resistant inorganic material (SiO₂) by the sol-gel method and producing a hybrid fluorescent thin film with an organic light-emitting material. Further, the goal is to improve dispersibility by covalently bonding an organic material having a vinyl group and an inorganic material by a radical reaction.
