Doping Eu 3+ /Sm 3+ into CaWO 4 :Tm 3+ , Dy 3+ phosphors and their luminescence properties, tunable color and energy transfer

Eu 3+ and Sm 3+ co-doped CaWO 4 :Tm 3+ , Dy 3+ phosphors were prepared by a hydrothermal method. Under different UV radiations, the tunable color and warm-white-light emissions are realized.
