Fabrication and ultraviolet photoresponse characteristics of ordered SnO(x )(x ≈ 0.87, 1.45, 2) nanopore films

Based on the porous anodic aluminum oxide templates, ordered SnO(x )nanopore films (approximately 150 nm thickness) with different x (x ≈ 0.87, 1.45, 2) have been successfully fabricated by direct current magnetron sputtering and oxidizing annealing. Due to the high specific surface area, this order...

Sumario:Based on the porous anodic aluminum oxide templates, ordered SnO(x )nanopore films (approximately 150 nm thickness) with different x (x ≈ 0.87, 1.45, 2) have been successfully fabricated by direct current magnetron sputtering and oxidizing annealing. Due to the high specific surface area, this ordered nanopore films exhibit a great improvement in recovery time compared to thin films for ultraviolet (UV) detection. Especially, the ordered SnO(x )nanopore films with lower x reveal higher UV light sensitivity and shorter current recovery time, which was explained by the higher concentration of the oxygen vacancies in this SnO(x )films. This work presents a potential candidate material for UV light detector. PACS: 81.15.Cd, 81.40.Ef, 81.70.Jb, 85.60.Gz.
