Abstract

The red long-lasting luminescence properties of the ZnGa 2 O 4:Cr 3+ spinel material are shown to be much improved when germanium or tin is substituted to the nominal composition. The resulting Zn 1+ x Ga 2–2 x (Ge/Sn) x O 4 (0 ≤ x ≤ 0.5) spinel solid solutions synthesized here by a classic solid st...
