Abstract
Luminescent properties of CaGa2S4 :Er polycrystals in the visible and infra red spectral ranges were investigated. The presence of two different point symmetries for Er3+ centers is well established by selective and polarized photoexcitation. The Ca thiogallate compound can be considered as a promisi ng material for optical communication purposes due to the intense Er3+ infr ared luminescence in the 1.55 mum range.
