Abstract:
1. A method for fabricating a thin film formed with a uniform single-size monolayer of spherical AZO nanoparticles, comprising the steps of: step A: mixing a material of zinc acetate, a material of aluminum acetate and a material of diethylene glycol so as to form a first solution while placing the first solution into a container to be heated to a predefined temperature for a first predefined period of time; step B: cooling the first solution in the container to a room temperature; step C: using a centrifugal apparatus for performing a high-speed centrifugal process upon the first solution so as to extract and obtain an upper layer solution from a centrifugal tube of the centrifugal apparatus to be used as a seed solution for posterior steps; step D: mixing a material of zinc acetate, a material of aluminum acetate, a material of diethylene glycol and the seed solution so as to form a second solution while placing the second solution into the container to be heated to a predefined temperature for a second predefined period of time; step E: cooling the second solution in the container to a room temperature; step F: using the centrifugal apparatus for performing a high-speed centrifugal process upon the second solution so as to extract and obtain a lower-layer sediment from the centrifugal tube of the centrifugal apparatus; step G: using a deionized water to rinse the lower-layer sediment; and step H: soaking the lower-layer sediment after rinsing into a solution of anhydrous alcohol so as to form spherical aluminum-doped zinc oxide (AZO) nanoparticles.
