CdxZn1−xO films in a wide range of Cd contents have been grown by reactive direct-current magnetron sputtering. At x ≤ 0.66, the sputtered CdxZn1−xO films are of single hexagonal phase. The optical band gap energies of the CdxZn1−xO films decrease from ∼3.3 eV at x = 0 to ∼1.8 eV at x = 0.66. Correspondingly, the near-band-edge photoluminescence is tuned in a wide visible region from ∼378 to 678 nm. Moreover, the ultraviolet irradiation enhanced PL from the CdxZn1−xO films has been observed.
► CdxZn1-xO films in a wide range of Cd contents were grown by reactive direct-current magnetron sputtering, which is a simple and widely used method.
► The optical band gap energies of CdxZn1-xO films were tuned from ∼ 3.3 eV to ∼ 1.8 eV.
► The ultraviolet irradiation enhanced photoluminescence from the CdxZn1-xO films was observed.
