C. Parlog et al., THE INCREASE OF FLUORESCENCE EFFICIENCY OF TIO2(EU3-FILMS BY CODOPINGWITH YTTRIUM() THIN), Revue Roumaine de Chimie, 40(10), 1995, pp. 1075-1082
The fluorescence spectroscopy of Eu3+ ions has been used as a probe of
the structural. changes that occur during the thermal treatment of Ti
O2(Eu3+) films. These changes reflect how the environment of the Eu3ions is modified during the initial film --> densified film transforma
tion. The variation of Eu3+ ion quantity introduced in the films and t
he addition of yttrium, as co-dopant were followed in the same way.
