In-situ investigations of the photoluminescence properties of SiO2/TiO2 binary and Boron-SiO2/TiO2 ternary oxides prepared by the sol-gel method and their photocatalytic reactivity... by Kyeong Youl Jung, Seung Bin Park, Masaya Matsuoka, Masakazu Anpo

“…The photoluminescence was found to be very sensitive to the presence of oxygen. These new photoluminescence completely disappeared by the addition of boron into SiO2/TiO2 binary oxide, since the emitting sites having a Ti–O–Si bond were destroyed and the new sites having B–O–Ti or Si–O–B bonds were constructed on the surface, being in agreement with the results obtained by FT-IR measurements. …”
