We measured ESR spectra of color centers on AgI-AgPO_3, AgI-Ag_2O-B_2O_3, AgI-Ag_2MoO_4, AgI-Ag_2WO_4, (CH_3)_4NI-(C_2H_5)_4NI-AgI (TMAI-TEAI-AgI) and its derivatives of superionic conducting glasses. In organic-inorganic mixed glasses, organic ion radicals were observed. They were not affected by ionic conductivity. On the contrary, Ag~2+, Ag~0 and aggregated ag~0 were observed in inorganic glasses. These color centers in inorganic glasses were affected by ionic conductivity.
