We report the evolution of superconductivity and the phase diagram of theKxFe2-ySe2-zTez (z=0-0.6) crystals grown by a simple one-step synthesis. Nostructural transition is observed in any crystals, while lattice parametersexhibit a systematic expansion with Te content. The Tc exhibits a gradualdecrease with increasing Te content from Tconset = 32.9 K at z = 0 to Tconset =27.9 K at z = 0.5, followed by a sudden suppression of superconductivity at z =0.6. Upon approaching a Te concentration of 0.6, the shielding volume fractiondecreases and eventually drops to zero. Simultaneously, hump positions in r-Tcurve shift to lower temperatures. These results suggest that isovalentsubstitution of Te for Se in KxFe2-ySe2 crystals suppresses thesuperconductivity in this system.
