Influence of Mg content on defect-related luminescence of undoped and doped wurtzite MgZnO ceramics
Undoped as well as Li-, Ag-, Cu- and Zn-doped MgxZn₁₋xO ceramics with x = 0–0.20 were sintered at 1000 °C. Defect-related photoluminescence (PL) and PL excitation spectra were measured at room temperature in 400–800 nm and 250–400 nm spectral ranges, accordingly. Two types of PL bands were observed:...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Undoped as well as Li-, Ag-, Cu- and Zn-doped MgxZn₁₋xO ceramics with x = 0–0.20 were sintered at 1000 °C. Defect-related photoluminescence (PL) and PL excitation spectra were measured at room temperature in 400–800 nm and 250–400 nm spectral ranges, accordingly. Two types of PL bands were observed: i) the bands, spectral positions of which were not influenced by the Mg content (Cu-related as well as selfactivated orange and red ones); ii) the bands, spectral positions of which exhibited some blueshift with increasing Mg content (Li- and Ag-related and self-activated green ones). It has been shown that used doping gives the possibility to obtain the phosphor with intense visible emission within the blue-yellow spectral range. |
