Abstract
- Eu 3+ doped BaMg 2 V 2 O 8 (BMVO) phosphor was synthesized via a high temperature solid-state reaction method. When λ ex = 318 nm and Eu 3+ was doped, the VO 4 3− peak at 545 nm decreased, and a characteristic Eu 3+ peak occurred together with a maximum at 620 nm. In conjunction with the decay curve, this indicates that the energy transfer from VO 4 3− to Eu 3+ . Upon doping with Eu 3+ , the phosphor becomes color-tunable. In addition, changing the temperature between 25 and 200 °C, BMVO:0.05Eu 3+ phosphor also becomes color-tunable. All results indicate that Eu 3+ doped BaMg 2 V 2 O 8 phosphor has many promising commercial applications. [ABSTRACT FROM AUTHOR]
