【Abstract】 The photorefraction and photovoltaic effects in Li-rich LiNbO₃co-doped with Mg and Fe were studied in comparision with that in LiNbO₃:Fe and Li-rich LiNbO₃:Mg.The results show that the photorefraction,pho-toconductivity and photovoltaic current of Li rich LiNbO₃:Mg:Fe are com-parable to those of Li-rich LiNbO₃:Mg,but are quite different from thoseof LiNbO₃:Fe.更多还原
