A novel violet/blue light-emitting device based on Ce(2)Si(2)O(7)

Rare-earth silicates are highly efficient materials for silicon-based light sources. Here we report a novel light-emitting device based on Ce(2)Si(2)O(7). Intense violet/blue electroluminescence was observed, with a turn-on voltage of about 13 V. The violet/blue emission is attributed to 4f–5d trans...

description Rare-earth silicates are highly efficient materials for silicon-based light sources. Here we report a novel light-emitting device based on Ce(2)Si(2)O(7). Intense violet/blue electroluminescence was observed, with a turn-on voltage of about 13 V. The violet/blue emission is attributed to 4f–5d transitions of the Ce(3+) ions in Ce(2)Si(2)O(7), which are formed by interfacial reaction of CeO(2) and Si. Electroluminescence and photoluminescence mechanisms of the Ce(2)Si(2)O(7) light-emitting device are also discussed.
