Ultraviolet-A-transparent aluminum-doped zinc oxide thin film electrodes by pulsed laser deposition.

The optoelectronics industry eagerly demands high-performance and low-cost ultraviolet (UV)-transparent electrodes to increase the efficiency of UV devices. However, aluminum-doped zinc oxide (AZO) is rarely considered a candidate for UV-transparent electrodes. Herein, this work fabricates AZO films by pulsed laser deposition and shows the potential of these films as UVA (320-400 nm)-transparent electrodes with Haacke's figure of merit up to ∼3.
