Synthesis of Eu ²⁺ and Dy ³⁺ Codoped Ba2MgSi2O7 Phosphor for Energy Storage

Abstract:

The Eu²⁺ and Dy³⁺ codoped Ba₂MgSi₂O₇ phosphor is synthesized via high temperature solid state reaction. The phase identification shows that the calcining temperature of this material is 1250°C. The photoluminescence analysis presents that the emission of this phosphors shifts from 440nm to 500nm as the phase become purity monocline Ba₂MgSi₂O₇. The decay curve and the TL illustrates that this materials shows a weak afterglow with a short duration owing to the deep trap. This deep trap has a strong ability to store the trapped carriers. So the application of this materials can be extended.
