Overview

Issue Title: Special Issue: Second Symposium of Renewable Energy and Sustainability: Research of Solar Materials in Mexico In this work, Sm^sup 3+^ doped [alpha]-Sr^sub 2^P^sub 2^O^sub 7^ phosphors without and with co-doping different charge compensation agents such as Li^sup +^, Na^sup +^, K^sup +^ and Cs^sup +^ were prepared by a solid state reaction at high temperature. The excitation and emission spectrum, decay curves, and the effect of charge compensation agents on the luminescence properties of [alpha]-Sr^sub 2^P^sub 2^O^sub 7^:Sm^sup 3+^ were investigated in detail. The results demonstrate that the as-prepared [alpha]-Sr^sub 2^P^sub 2^O^sub 7^:Sm^sup 3+^ phosphors can be efficiently excited by ultraviolet light, and the emission spectrum consists of three emission peaks at 561, 601, 642 nm. By introducing the charge compensator M^sup +^ (M^sup +^ = Li^sup +^, Na^sup +^, K^sup +^, Cs^sup +^) into the [alpha]-Sr^sub 2^P^sub 2^O^sub 7^:Sm^sup 3+^ phosphor, the emission intensity can be enhanced remarkably.
