Abstract
An ultraviolet photodetector for a sensor device includes a film deposited on a substrate. The film includes a compositionally graded magnesium-zinc oxide having a ratio of magnesium-to-zinc that decreases between a portion of the film adjacent to the substrate and a portion of the film opposite the substrate for shifting the peak absorption of the film toward the visible wavelengths of the electromagnetic spectrum.
