Influence of isovalent doping on the cathodoluminescence of Li₂B₄O₇:A (A = K, Cu, Ag) single crystals
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 Ll 2B40 7 is the annihilation of self-trapped excitons (STE). The Cu and Ag impurities have their intrinsic emission bands in CL spectr...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | 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 Ll 2B40 7 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. |
