The Zn_{1-x}Mn_xTe_{1-y}O_y alloy was prepared using a rapid crystallization technique. X-ray diffraction measurements were used to estimate the oxygen doping level. It is demonstrated that the oxygen solubility in Zn_{1-x} Mn_xTe_{1-y}O_y alloys greatly depends on the manganese concentration. No oxygen related effects were observed in the manganese free samples. The highest value of the oxygen molar fraction (y) achieved in the present study was 0.0023 in a sample having manganese fraction (x) of 0.056. The decrease in the alloy band gap was observed with increasing oxygen content. The oxygen-related trap level in Zn_{1-x}Mn_xTe_{1-y}O_y was found to be strongly shifted with respect to that in ZnTe_{1-y}O_y. The shift is assigned to a creation of complex (Mn_xO) traps.
