Research on the Luminescence and Temperature Quenching Properties of BaSi2O2N2:Eu2+ Phosphor.

The BaSi2O2N2:Eu2+ phosphor is synthesized by solid state reaction. The luminescent properties and temperature quenching performance of BaSi2O2N2:Eu2+ phosphor are measured. It has been demonstrated that the Eu2+ doped BaSi2O2N2 phosphor shows efficient green emission with peak at around 492 nm. With the incorporation of La3+ and Y3+, the quantum efficiency of BaSi2O2N2:Eu2+ and the temperature quenching performance of BaSi2O2N2:Eu2+ is changed, which is explained from the electronic structure view.
