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:...
