Study on the morphological and optical properties of porous anodic alumina

Porous anodic alumina (PAA) has been investigated extensively over the last few decades due to its effectiveness and simplicity to grow self-ordered nanopores, which is excellent as a template for nanostructures fabrication. To introduce more feasibilities in anodizing PAA, the attempt to fabricate...
