Abstract

Zn_1-xMg_xO films prepared with different x were deposited on substrates by the sol-gel technique. X-ray photoelectron spectroscopy, x-ray diffraction, atomic force microscopy, photoluminescence and conductivity measurements were used to characterize the Zn_1-xMg _xO films. The yield in the intensity of the band-edge luminescence (BEL) is seen to increase up to 21-fold for Zn_0.94Mg_0.06O and up to 4-fold for Zn_0.958Mg_0.042O compared with the Zn_0.973Mg_0.027O film. The enhanced BEL intensity has been attributed to an increase in the nonradiative recombination lifetime, a reduction in the oxygen-vacancy related defects and a reduction in the refractive index of the Zn_1-xMg_xO film.
