Energy transfer mechanism and color-tunable luminescence properties of Eu3+-doped BaMg2V2O8 vanadate phosphors
Eu3+ doped BaMg2V2O8 (BMVO) phosphor was synthesized via a high temperature solid-state reaction method. When lambda(ex) = 318 nm and Eu3+ was doped, the VO43- peak at 545 nm decreased, and a characteristic Eu3+ peak occurred together with. a maximum at 620 nm. In conjunction with the decay curve, this indicates that the energy transfer from VO43- to Eu3+. Upon doping with Eu3+, the phosphor becomes color-tunable. In addition, changing the temperature between 25 and 200 degrees C, BMV0:0.05Eu(3+) phosphor also becomes color -tunable. All results indicate that Eu3+ doped BaMg2V2O8 phosphor has many promising commercial applications. (C) 2016 Elsevier B.V. All rights reserved.
