Abstract
We report on continuous wave and time-resolved photoluminescent characteristics of Mg(x)Zn(1-x) O (0 <= x <= 0.18) alloy nanorods grown on Si substrates using catalyst-free metal-organic chemical vapor deposition. Low temperature time- integrated photoluminescence (PL) spectra of the alloy nanorods clearly exhibited a dominant PL peak of a single Mg(x)Zn(1-x)O phase without showing any PL peak from ZnO. In addition, dominant PL peak positions of the alloy nanorods were blueshifted with increasing Mg content in the nanomaterials. Using temperature-dependent PL spectra and time- resolved PL spectra of Mg(x)Zn(1-x)O nanorods, we discuss the composition fluctuations in Mg(x)Zn(1-x)O(0 <= x <= 0.18) nanorods.
