H. Nakajima et al., Influence of the adsorbate and the crystal structure on the photoluminescence property of TiO2 powder in air with ethanol vapor at room temperature, CHEM LETT, (4), 2001, pp. 304-305
The influence of crystal structure and photocatalytic (PC) reaction on phot
oluminescence (PL) of several TiO2 powders has been studied at room tempera
ture. The PL intensity of the rutile TiO2 powders increased significantly i
n proportion to t1/2 by adding ethanol vapor, while those of the anatase Ti
O2 powders increased slowly. This observation can be explained based on the
difference in their PC activities.
