Patent ID: 8173205

Claim:
A method for fabricating a ZnO thin film comprising: preparing a precursor solution for ZnO thin film in a sol-form by using zinc hydroxide nitrate (Zn 5 (OH) 8 (NO 3 ) 2 .2H 2 O); and coating the precursor solution for ZnO thin films on a substrate; drying the coated precursor solution to form a ZnO thin film; and curing the ZnO thin film, wherein the step of preparing the precursor solution for ZnO thin film in a sol-form comprises: mixing an aqueous Zn(NO 3 ) 2 .6H 2 O solution and NaOH to synthesize Zn 5 (OH) 8 (NO 3 ) 2 .2H 2 O; and mixing the Zn 5 (OH) 8 (NO 3 ) 2 .2H 2 O and a stabilizer or modifier in a polar solvent while stirring.
