摘要：
Disordered Sm3+ doped Y3ScxAl5-xO12 (Sm:YS(x)AG) polycrystalline ceramics with compositional parameter x = (0.05, 0.5, 1, 2) and different Sm3+ ions concentrations were obtained by solid state reaction method. XRD investigations show the linear increase of the lattice constant with compositional parameters x. New spectroscopic data obtained from high resolution optical absorption and emission spectra of Sm3+ doped YS(x)AG ceramics reveal composition effects on Sm3+ optical spectra: modification of the shapes and shifts of the lines, presence of the additional satellites and unresolved multicenter structure, etc. The analysis of these data allowed us to establish a partial structure of Sm3+ energy levels in Sm:YS(x)AG (x = 2) ceramics. The emission kinetics of the (4)G(5/2) level for different Sm3+ concentrations and Sc content in Sm:YS(x)AG were measured and analyzed. (C) 2016 Elsevier B.V. All rights reserved.
