Abstract: The effect of Br- and I- on the Mn2+ and Cu+ lumin escence center of Zn S:Mn,Cu*X was investigated. The luminescence spectra and excitation luminescenc e waveform was investigated. We found the evidence effect of Br- on the half life of excitation stater of Mn2+ and Cu+ luminescence center.The lumine s cence intensity of Cu+ green luminescence center increase with Br- increase. The half life of excitation stater of Cu2+ decrease with the Br- increas e.The half life of excitation stater of Mn2+ increase with the Br+ incre ased.
