摘　　要：Nanocrystalline titania as photocatalyst has attracted considerable attention for its potential use in environmental cleaning.Recently,lanthanide ions doped titania samples have been shown to increase the photocatalytic efficiency of selected reactions.In this work,TiO2 nanoparticles doped with Er3+ were prepared via an ultrasonic assisted sol-gel method.The optical properties of the samples were determined by photoacoustic(PA) spectroscopy.It was found that the absorption edge shifted to lower wavelength w...Nanocrystalline titania as photocatalyst has attracted considerable attention for its potential use in environmental cleaning.Recently,lanthanide ions doped titania samples have been shown to increase the photocatalytic efficiency of selected reactions.In this work,TiO2 nanoparticles doped with Er3+ were prepared via an ultrasonic assisted sol-gel method.The optical properties of the samples were determined by photoacoustic(PA) spectroscopy.It was found that the absorption edge shifted to lower wavelength w...
