Controlled spatial separation of Eu ions in layered silicates with different layer thickness.
The photoluminescence of a series of Eu(3+) doped layered silicates (kanemite, octosilicate, magadiite and kenyaite) was examined; it was found that layer thickness affected the luminescence intensity, suggesting the possible effects of the spatial separation of Eu(3+) in the direction perpendicular to silicate sheets on the luminescence self-quenching.
