We report a simple dielectric barrier discharge device for generating slot homogeneous plasma in atmospheric pressure air. It consists of two parallel water electrodes with a distance adjusting micrometer. With increasing the applied voltage, the discharge becomes homogeneous. The electron temperature, vibrational temperature (T(V)) of N(2), and rotational temperature (T(R)) of N(2)( ) are estimated by optical emission spectroscopy. Both T(V) and T(R) remain unchanged along the slot in the homogeneous discharge regime. The trend of the T(V) with respect to the applied voltage is opposite from that of T(R), while the electron temperature keeps constant with the increasing applied voltage.
