| Abstract: | A simple and convenient synthesis approach for metal oxide nanodot films has been reported. Porous anodic alumina (PAA) films with ordered nanocave arrays were fabricated firstly and used as template materials. Then the metals were evaporated on the surface of the PAA template following with oxidization in air. The prepared metal oxide thin films have highly ordered hemispherical nanodot arrays arranged in a hexagonal pattern. The density of the nanodots in the array is about 2×1013 /m2 with dot diameters and heights about 100 nm and 45 nm, respectively. |
