Zinc oxide nanomaterial and preparation method thereof and semiconductor device

A preparation method of a zinc oxide (ZnO) nanomaterial comprising:

• preparing a mixed solution of a ZnO nanoparticle and a surface ligand;
• and
• causing the ZnO nanoparticle to react with the surface ligand in the mixed solution to prepare ZnO nanoparticle having the surface ligand bonded thereto;
• wherein:
• the surface ligand has a structure of
• R1, R2, R3, R4, and R5 are independently selected from at least one of hydrogen, alkoxy group with a carbon number of one to three, or amino group;
• and
• R1, R2, R3, R4, and R5 include:
• one to three alkoxy groups with a carbon number of one to three;
• and
• zero to one amino group.

A semiconductor device comprising:

• an anode and a cathode arranged oppositely to each other;
• an active layer arranged between the anode and the cathode;
• and
• an electron transport layer arranged between the active layer and the cathode;
• wherein:
• a material of the electron transport layer includes a zinc oxide (ZnO) nanomaterial;
• the ZnO nanomaterial includes:
• a ZnO nanoparticle;
• and
• a surface ligand bonded to the ZnO nanoparticle, the surface ligand being at least one selected from m-methoxybenzamide, o-methoxybenzamide, p-ethoxybenzamide, m-ethoxybenzamide, o-ethoxybenzamide, 2,5-dimethoxybenzamide, 3,5-dimethoxybenzamide, 2,4-dimethoxybenzamide, 3,4-dimethoxybenzamide, or 5-amino-4-methoxybenzamide
