Influence of Sm~(3+) in alkaline metals Eu~(3+) molybdate/tungstate red phosphor: A review

摘要

This paper reviews on previous and on-going works relating to the interaction of Eu~(3+) and Sm~(3+) used in AGd_((1-x))Eu_x(MO_4)_2 where (A=Li~+, K~+ and Na~+) and (M=Mo and W) in alkaline metals red phosphors - AGd_((1-x))Eu_xSm_y(MoO_4)_2. A literature review in terms of its crystal structures as well its effects on the photoluminescence properties of the phosphor is elucidated herein. The outcome from this review concludes that there is a large possibility that a more efficient red phosphor can be obtained by introducing Sm~(3+) on AGd_((1-x))Eu_xSm_y(MoO_4)_2.
