Abstract
Refinements introduced in luminescent screens provided with a luminescent cerium aluminate that has a hexagonal crystalline structure, corresponding to that of Β -alumina, characterized in that the aluminate is activated with terbium and satisfies the signature (Ce1-xy.LaxTby) 2O3.nAl2O3, where up to 25 mol% of Al2O3 may be replaced by Ga2O3 and where 8 <= n <= 13 0 <= x <= 0.70 0.001 <= and <= 0.30 x + y <= 0.90.
