Novel SnO 2/MnO co-doped phosphate glasses with tunable luminescence properties

Abstract

In the present work, novel SnO 2/MnO co-doped phosphate glasses are prepared and their tunable luminescence properties are presented. Under excitation at 267 nm, all co-doped glasses exhibit an assembly of SnO 2 blue emission at 420 nm and MnO red emission around 600 nm. With the increasing of MnO concentration, intensity of the SnO 2 blue emission decreases while that of MnO red emission increases. With the increasing of SnO 2 concentration, both SnO 2 and MnO emissions are greatly enhanced, resulting in the white light emitting.
