Highlights: • We have firstly synthesized a single-phased Ca{sub 14}Al{sub 10}Zn{sub 6}O{sub 35}:Bi{sup 3+},Sm{sup 3+} phosphor. • Different measurement support the energy transfer from Bi{sup 3+} to Sm{sup 3+}. • Based on the energy transfer, tunable emission were realized. - Abstract: A series of Bi{sup 3+}, Sm{sup 3+}-codoped Ca{sub 14}Al{sub 10}Zn{sub 6}O{sub 35} phosphors were synthesized via conventional high temperature solid-state method. The crystal structure, morphology, photoluminescence and energy transfer mechanism from Bi{sup 3+} to Sm{sup 3+} were investigated in detail. A broad blue emission band due to {sup 3}P{sub 1} → {sup 1}S{sub 0} transition of Bi{sup 3+} was observed in the Bi{sup 3+} single-doped Ca{sub 14}Al{sub 10}Zn{sub 6}O{sub 35} sample, the Ca{sup 2+} position are verified to be replaced by Bi{sup 3+} and the corresponding concentration quenching mechanism was dipole-dipole interaction. The considerable spectral overlap between the broad emission band of Bi{sup 3+} around 350–550 nm and the excitation band of Sm{sup 3+} supports the energy transfer from Bi{sup 3+} to Sm{sup 3+}. This investigation will contribute to the comprehension of interactions between Bi{sup 3+} and Sm{sup 3+}. These results reveal the potential application of Bi{sup 3+}, Sm{sup 3+} co-doped phosphor in UV light-emitting diodes and artificial light in plant.
