摘要

In a recent paper entitled "Low temperature synthesis wide optical band gap Al and (Al, Na) co-doped ZnO thin films" published in this journal, Wang et al. studied the optical property of Al and (Al, Na) co-doped ZnO thin films prepared by sol-gel technique [1 ]. One of the most important conclusions of their work is the declaration of obtaining doped ZnO thin films with optical band gap as wide as 3.83-3.94 eV. The authors drew this conclusion based on the calculation of the transmittance spectra using plots of (ahv)~2 versus hv. In my opinion, however, their interpretation of the transmittance spectra is definitely wrong.
