    Comparison of Ultraviolet Shielding Effect of Nano TiO2 and Nano ZnO

    Nano zinc oxide and nano titanium oxide are two important and widely used physical sunscreens. Their principle of shielding ultraviolet rays is to absorb and scatter ultraviolet rays. Because they are all N-type semiconductors, the band gap of rutile nano-titanium oxide is 3.0 eV, and the band gap of nano-zinc oxide is 3.2 eV. When irradiated by ultraviolet rays, electrons in the valence band can ...
