Source abstract
Abstract
Abstract We present a preliminary study concerning the luminescence properties of polycrystalline ceramics with stoichiometric formula Sr(ErxYbyLa1-x-y)Ga3O7 (x = 0.005, 0.01; y = 0.03, 0.04) obtained by solid-state reaction and normal sintering method. Spectroscopic characteristics were investigated in order to assess the potential of this material as phosphor for visible domain. Red (660 nm, 4F9/2 → 4I15/2), green (550 nm, (2H11/2,4S3/2) → 4I15/2), violet (408 nm, 2H9/2 → 4I15/2) and ultraviolet (380 nm, 4G11/2 → 4I15/2) upconversion luminescence were obtained for the first time in Sr(ErxYbyLa1-x-y)Ga3O7 ceramic samples, by pumping at 973 nm.
