Colored and Translucent Chalcogenide-Oxide Nanocomposite Films Prepared by Spin Coating and Reflow Processes

This work reports on the fabrication of colored and translucent chalcogenide-oxide nanocomposite films, and their optical properties for use in transparent photoelectric device applications. Spin coating method from ZrO2 colloid solutions was used to deposit ZrO2 nanoparticle layers on substrates. GeTe chalcogenide thin films were subsequently deposited by rf sputtering, and were postannealed to form nanocomposite films. Color variation was achieved by the application of the nanocomposite films to glass substrates, which implies that the nanocomposite films can be applied to transparent photoelectric devices to improve aesthetic appearance by adjusting colors.
