Novel SnO2/MnO co-doped phosphate glasses with tunable luminescence properties

In the present work, novel SnO₂/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 SnO₂ blue emission at 420 nm and MnO red emission around 600 nm. With the increasing of MnO concentration, intensity of the SnO₂ blue emission decreases while that of MnO red emission increases. With the increasing of SnO₂ concentration, both SnO₂ and MnO emissions are greatly enhanced, resulting in the white light emitting.
