The synthetic ZnAl_2O_4 spinels doped with Cr^{3+} ions are prepared from ZnSO_4, Al_2(SO_4)_3, and Cr_2(SO_4)_3. The spinel single phase is detected from X-ray diffraction. Luminescence properties of Cr^{3+} in ZnAl_2O_4 were studied by low temperature luminescence and decay measurements. Four luminescence lines at 14570, 14520, 14460, and 14330 cm^{-1} were found to originate from structure distortion and the line at 14175 cm^{-1} - from chromium pairs. The broad emission band at about 13540 cm^{-1} is considered to arise from a new Cr^{3+} center in ZnCr_2O_4.
