Preparation and optical properties of afterglow Sr2MgSi2O7:Eu2+, Dy3+ electrospun nanofibers

One-dimensional Sr2MgSi2O7:Eu2+, Dy3+ nanofibers were synthesized by a simple and cost-effective electrospinning technique. The samples were characterized by XRD, FT-IR, TG-DTA, SEM, TEM and PL. The XRD and SEM results show single crystal nanofibers of Sr2MgSi2O7:Eu2+, Dy3+ with an average diameter of 200 nm were obtained by electrospinning preparation and heat treatment at 1150 degrees C for 5 h. The single crystal structure of Sr2MgSi2O7:Eu2+ nanofiber was discussed. The luminescent properties, long lasting performance and formation mechanism are also investigated. (C) 2015 Elsevier B.V.
