• •The solution limit of F in Sm(O,F)BiS2 single crystals was less than 20 at%.•F concentrations of Sm(O,F)BiS2 single crystals were hardly controlled.•Possibility in the existence of intrinsic stable phase for Sm(O,F)BiS2 was revealed.•Superconductivity of Sm(O,F)BiS2 single crystals was shown at around 5 K. Sm(O,F)BiS2 superconducting single crystals with various nominal F contents have been grown using KI-KCl flux. The solid solution limit of F at the O-site in Sm(O,F)BiS2 single crystals was approximately less than 20 at%. F concentrations of Sm(O,F)BiS2 single crystals were hardly controlled by nominal F contents. It suggests the existence of intrinsic stable phase. Superconductivity was shown at around 5 K. Superconducting transition temperature with zero resistivity were increased with increasing nominal F contents within less than 70 at% in O-site, despite similar F concentration and c-axis lattice constants.
