Silver nanoprisms grown into structural colors by high power LEDs

From Applied Science.

How to chemically synthesize silver nanoparticles, then grow them into triangular nanoprisms with light from a variety of LEDs. Each color LED creates a different size nanoprism, which has its own characteristic color.
