Eu3+ doped yttrium hydroxide nanosheets were successfully synthesized from layer compound of Y2(OH)5NO3 doped by Eu3+. Firstly layer compound of Y2(OH)5NO3 doped by Eu3+ was obtained by hydrothermal reaction. After ion exchange reaction with SDS, the layer space became lager. Furthermore stable nanosheet sol was prepared after exfoliation. The structure of layer compound and nanosheets were determined by XRD, TEM. The luminescence properties of yttrium hydroxide nanosheets doped with Eu3+ were examined; the relationship between structure and spectra was discussed.

Tb3+ doped Yttrium hydroxide nanosheets were successfully synthesized from layer compound of Y2(OH)5NO3 doped by Tb3+. Layer compound was obtained by hydrothermal reaction at 120°. After ion exchange reaction with sodium benzoate under the microwave condition, the layer space of the compound increases from 0.907 nm to 1.452 nm. stable nanosheets sol was obtained after exfoliation under ultrasonic condition. The structure of layer compound and the morphology of nanosheets were determined by XRD,SEM, Zeta Size, Zeta Potential, TEM and FL. The luminescence properties of terbium hydroxide nanosheets doped with Tb3+ were examined; the relationship between structure and spectra was discussed.

Eu3+ doped terbium hydroxide nanosheets were successfully synthesized from layer compound of Tb2(OH)5NO3·1.5H2O doped by Eu3+. Firstly layer compound of Tb2(OH)5NO3·1.5H2O doped by Eu3+ was obtained by hydrothermal reaction at 1200 . After ion exchange reaction with SDS under the microwave condition, the layer space of the compound increases from 0.907 nm to 2.34 nm. Furthermore stable nanosheet sol was obtained after exfoliation under ultrasonic condition. At the mean time we discovered that microwave and ultrasonic method can greatly shorten the preparation time. The structure of layer compound and the morphology of nanosheets were determined by XRD and TEM. The luminescence properties of terbium hydroxide nanosheets doped with Eu3+ were examined; the relationship between structure and spectra was discussed

The formation of reactive oxygen species due to irradiation by a visible light of the polythiophene deposited in ZSM-5 zeolite channels in aqueous medium has been studied. Polymerization of thiophene was carried out in zeolite channels after the ion-exchange reaction of Na+ for Fe3+. By means of EPR spectroscopy, the temporarily generated 1O2 in irradiated aqueous medium was proved. The formation of O2-• was confirmed by the reduction of Fe3+-cytochrome c. Irradiation led to the water reduction to hydrogen.
