Abstract Superconductivity below 0.3 K and a charge-density-wave-like (CDW-like) anomaly at 280 K were observed in EuBiS$_{2}$F recently. Here we report a systematic study of structural and transport properties in Eu$_{0.5}Ln_{0.5}$BiS$_{2}$F ($Ln$ = La, Ce, Pr, Nd, Sm) by electrical resistivity, magnetization, and specific heat measurements. The lattice constants have a significant change upon rare earth substitution for Eu, suggesting an effective doping. As $Ln$ is changed from Sm to La, the superconducting transition temperature $T_{\rm c}$ increases from 1.55 K to 2.8 K. In contrast to the metallic parent compound, the temperature dependence of electrical resistivity displays semiconducting-like behavior for all the Eu$_{0.5}Ln_{0.5}$BiS$_{2}$F samples. Meanwhile, the CDW-like anomaly observed in EuBiS$_{2}$F is completely suppressed. Unlike the mixed valence state in the undoped compound, Eu ions in these rare-earth-doped samples are mainly divalent. A specific anomaly at 1.3 K resembling that in EuBiS$_{2}$F suggests the coexistence of superconductivity and spin glass state for Eu$_{0.5}$La$_{0.5}$BiS$_{2}$F. Coexistence of ferromagnetic order and superconductivity is found below 2.2 K in Eu$_{0.5}$Ce$_{0.5}$BiS$_{2}$F samples. Our results supplies a rich diagram showing that many interesting properties can be induced in BiS$_{2}$-based compounds.
