Topology of the zeolite frameworks and Auger spectra of their silver clusters.

Researchers have discovered a new phosphor that could make next-generation fluorescent and LED lighting even cheaper and more efficient. The team used highly luminescent clusters of silver atoms and the porous framework of minerals known as zeolites. Silver clusters consist of just a few silver atoms and have remarkable optical properties. However, current applications are limited, because the clusters tend to aggregate into larger particles, thus losing the interesting optical properties.

Phosphor is the luminescent material critical to many lighting applications, especially LEDs. Most white LEDs are in fact blue LEDs with a phosphor coating.

Prof Hofkens and his team have now found a way to keep the silver clu...
