摘要：
The study results of cathodoluminescence (CL) of isovalently doped Li2B4O7:A single crystals (A = K, Cu, Ag) are reported. The main CL emission mechanism of undoped Li2B4O7 is the annihilation of self-trapped excitons (STE). The Cu and Ag impurities have their intrinsic emission bands in CL spectra which are overlaid onto Li2B4O7 STE band about 3.65 eV. The models of CL centers and mechanisms in Li2B4O7:A single crystals are proposed.
