"We have essentially developed tunable photonic materials whose properties can be manipulated by changing their orientation with external fields," said Yin, an assistant professor of chemistry. "These nanorods with configurable internal periodicity represent the smallest possible photonic structures that can effectively diffract visible light. This work paves the way for fabricating magnetically responsive photonic structures with significantly reduced dimensions so that color manipulation with higher resolution can be realized."
Applications of the technology include high-definition pattern formation, posters, pictures, energy efficient color displays, and devices like traffic signals that routinely use a set of colors. Other applications are in bio- and chemical sensing as well as biomedical labeling and imaging. Color displays that currently cannot be seen easily in sunlight – for example, a laptop screen – will be seen more clearly and brightly on devices that utilize the nanorod technology since the rods simply diffract a color from the visible light incident on them.
