Synthesis and luminescence properties of La2-xRExSn2O7 (RE = Eu and Dy) phosphor nanoparticles

Abstract La 2− x RE x Sn 2 O 7 (RE = Eu and Dy) phosphor nanoparticles were synthesized via a simple coprecipitation method for the first time. The size of the as-synthesized nanocrystalline phosphor is smaller than 100 nm. The luminescence properties of Eu 3+ -doped and Eu 3+ , Dy 3+ -codoped La 2 Sn 2 O 7 phosphor were investigated. They had the different emission rule comparing with the former reports.
